Keeping the Heart #1 — John Flavel

Keeping the Heart Through Diligent Watchfulness

ON KEEPING THE HEART. A book by the Puritan John Flavel Keep thy heart with all diligence, for out of it are the issues of life, Proverbs 4 .23. The heart of man is his worst part before he is regenerated, and the best afterwards.

It is the seat of principles and the fountain of actions. The eye of God is, and the eye of the Christian ought to be principally fixed upon it. The greatest difficulty in conversion is to win the heart to God, and the greatest difficulty after conversion is to keep the heart with God.

Here lies the very force and stress of religion. Here is that which makes the way to life a narrow way, and the gate of heaven a straight gate. Direction and help in this great work are the scope of the text, wherein we have, first, an exhortation, Keep thy heart with all diligence.

2. The reason or motive in forcing it, for out of it are the issues of life. In the exhortation I shall consider, first, the matter of the duty, secondly, the manner of performing it. 1. The matter of the duty, Keep thy heart.

Heart is not here taken properly for the noble part of the body, which philosophers call the first that lives and the last that dies, but by heart, in a metaphor, the scripture sometimes represents some particular noble faculty of the soul.

In Romans 1 .21 it is put for the understanding, Their foolish heart, that is, their foolish understanding was darkened. Psalm 119 .11. It is put for the memory, Thy word have I hid in my heart. In 1 John 3 .10 it is put for the conscience, which includes both the light of the understanding and the recognitions of the memory.

If our heart condemn us, that is, if our conscience, whose proper office it is to condemn. But in the text we are to take it more generally for the whole soul or inner man. What the heart is to the body, that the soul is to the man, and what health is to the heart, that holiness is to the soul.

The state of the whole body depends upon the soundness and vigor of the heart, and the everlasting state of the whole man upon the good or ill condition of the soul. By keeping the heart we are to understand the diligent and constant use of all holy means to preserve the soul from sin, and maintain its sweet and free communion with God.

I say constant for the reason added in the text extends the duty to all the states and conditions of a Christian's life, and makes it binding always. If the heart must be kept, because out of it are the issues of life, then as long as these issues of life do flow out of it, we are obliged to keep it.

Lavator on the text will have the word taken from a besieged garrison, beset by many enemies without and in danger of being betrayed by treacherous citizens within, in which danger the soldiers, upon pain of death, are commanded to watch, and though the expression, Keep thy heart, seems to put it upon us as our work, yet it does not imply a sufficiency in us to do it.

We are as able to stop the sun in its course, or to make the rivers run backward, as by our own will and power to rule and order our hearts. We may as well be our own saviors, as our own keepers. And yet Solomon speaks properly enough when he says, Keep thy heart, because the duty is ours, though the power is of God.

What power we have depends upon the exciting and assisting strength of Christ. Grace within us is beholden to grace without us. Without me ye can do nothing. So much for the matter of the duty. 2. The manner of performing it is with all diligence.

The Hebrew is very emphatic. Keep with all keeping, or keep, keep, set double guards. This vehemence of expression which of the duty is urged, plainly implies how difficult it is to keep our hearts, how dangerous to neglect them.

The motive to this duty is very forcible and weighty, for out of the heart are the issues of life. That is, the heart is the source of all vital operations. It is the spring and original of both good and evil, as the spring in a watch that sets all the wheels in motion.

3. The heart is the treasury, the hand and tongue but the shops. What is in these comes from that. The hand and tongue always begin where the heart ends. The heart contrives and the members execute. A good man out of the good treasure of his heart brings forth that which is good, and an evil man out of the evil treasure of his heart brings forth that which is evil.

For out of the abundance of the heart his mouth speaketh. So then, if the heart err in its work, these must miscarry in theirs. For heart errors are like the errors of the first concoction, which cannot be rectified afterward, or like the misplacing and inverting of the stamps and letters in the press, which must cause so many errata in all the copies that are printed.

O then, how important a duty is that which is contained in the following. 4. Proposition. The keeping and right managing of the heart in every condition is one great business of a Christian's life. What the philosophers say of waters is as properly applicable to hearts.

It is hard to keep them within any bounds. God has set limits to them, yet how frequently do they transgress not only the bounds of grace and religion, but even of reason and common honesty. This is that which affords the Christian manner of labor and watchfulness to his dying day.

It is not the cleaning of the hand that makes the Christian, for many a hypocrite can show as fair a hand as he, but the purifying, watching, and right ordering of the heart. This is the thing that provokes so many sad complaints, and costs so many deep groans and tears.

It was the pride of Hezekiah's heart that made him lying in the dust, mourning before the Lord. It was a fear of hypocrisies invading the heart that made David cry, Let my heart be sound in thy statutes, that I be not ashamed.

It was the sad experience he had of the divisions and distractions of his own heart in the service of God that made him pour out the prayer, Unite my heart to fear thy name. The method in which I propose to improve the proposition is this.

First, I shall inquire what the keeping of the heart supposes and imports. Secondly, assign a number of reasons why Christians must make this a leading business of their lives. Thirdly, point out those seasons which especially call for this diligence in keeping the heart.

And fourthly, apply the whole. First, I am to consider what the keeping of the heart supposes and imports. To keep the heart necessarily supposes a previous work of regeneration, which is set the heart right by giving it a new spiritual inclination.

For as long as the heart is not set right by grace as to in habitual frame, no means can keep it right with God. Self is the poise of the unrenewed heart, which biases and moves it in all its designs and actions.

And as long as it is so, it is impossible that any external means should keep it with God. Man originally was of one constant uniform frame of spirit, held one straight and even course. Not one thought or faculty was disordered.

His mind had a perfect knowledge of the requirements of God, his will a perfect compliance therewith. All his appetites and powers stood in a most obedient subordination. Man, by the apostasy, has become a most disordered and rebellious creature, opposing his Maker as a first cause or self-dependence as the chief good, by self-love as the highest Lord, by self-will, and at the last end, by self-seeking.

Thus he is quite disordered and all his actions are irregular. But by regeneration the disordered soul is set right, this great change being, as the Scripture expresses it, the renovation of the soul after the image of God, in which self-dependence is removed by faith, self-love by the love of God, self-will by subjection and obedience to the will of God, and self-seeking by self-denial.

The darkened understanding is illuminated, the refractory will sweetly subdued, the rebellious appetite gradually conquered. Thus the soul which sin had universally depraved is by grace restored. This being presupposed, it will not be difficult to apprehend what it is to keep the heart, which is nothing but the constant care and diligence of such a renewed man to preserve his soul in that holy frame to which grace has raised it.

For though grace has, in a great measure, rectified the soul and given it an habitual heavenly temper, yet sin often actually discomposes it again, so that even a gracious heart is like a musical instrument, which, though it be exactly tuned, a small matcher brings it out of tune again.

Yea, hang it aside but a little, and it will need settling again before another lesson can be played upon it. If gracious hearts are in a desirable frame in one duty, yet how dull, dead, and disordered when they come to another.

Therefore every duty needs a particular preparation of the heart, if thou prepare thine heart and stretch out thine hands toward him, and so on. To keep the heart, then, is carefully to preserve it from sin, which disorders it, and maintains that spiritual frame which fits it for a life of communion with God.

Examining and Humbling the Heart

This includes in it six particulars. 1. Frequent Observation of the Frame of the Heart. Carnal and formal persons take no heed to this. They cannot be brought to confer with their own hearts. There are some people who have lived forty or fifty years in the world, and have had scarcely one hour's discourse with their own hearts.

It is a hard thing to bring a man and himself together on such business, but saints know those soliloquies to be very salutary. The heathen can say the soul is made wise by sitting still in quietness.

Though bankrupts care not to look into their accounts, yet upright hearts will know whether they go backward or forward. I commune with mine own heart, says David. The heart can never be kept until his case be examined and understood.

2. It includes deep humiliation for heart evils and disorders. Thus has Achaia humbled himself for the pride of his heart. Thus the people were ordered to spread forth their hands to God in prayer, realizing the plague of their own hearts.

Upon this account, many an upright heart has been laid low before God. Oh, what an heart have I! Saints have in their confession pointed at the heart, the pain place. Lord, here is a wound. It is with the heart well kept as it is with the eye.

If a small dust get into the eye, it will never cease twinkling and watering till it is wefted out. So the upright heart cannot be at rest till it has weft out its troubles and poured out its complaints before the Lord.

3. It includes earnest supplication and instant prayer for purifying and rectifying grace when sin has defiled and disordered the heart. Cleanse thou me from secret faults. Unite my heart to fear thy name.

Saints have always made such petitions before the throne of God's grace. This is a thing which is most pleaded by them with God. When they are praying for outward mercies, perhaps their spirits may be more remiss.

But when it comes to the heart's case, they extend their spirits to the utmost, fill their mouths with arguments, weep, and make supplication. Oh, for a better heart! Oh, for a heart to love God more, to hate sin more, to want more evenly with God!

Lord, deny not to me such a heart. Whenever thou deny me, give me a heart to fear thee, to love and delight in thee, if I beg my bread in desolate places. It is observed of an eminent saint that when he was confessing sin, he would never give over confessing until he had some felt brokenness of heart for that sin, and when praying for any spiritual mercy, would never give over that suit till he had obtained some relish of that mercy.

4. It includes the imposing of strong engagement upon ourselves to walk more carefully with God, and avoid the occasions in which the heart may be induced to sin. While advice and deliberate vows are, in some cases, very useful to guard the heart against some special sin.

I have made a covenant with mine eyes, says Job. By this means holy men have overawed their souls, and preserved themselves from defilement. 5. It includes a constant and holy jealousy over our own hearts.

Quick-sighted self-jealousy is an excellent preservative from sin. He that will keep his heart must have the eyes of the soul awake and open upon all the disorderly and tumultuous stirrings of his affections.

If the affections break loose and the passions be stirred, the soul must discover it and suppress them before they get to a height. 6. O my soul, does thou well in this? My tumultuous thoughts and passions, where is your commission?

Happy is a man that thus feareth always. By this fear of the Lord it is that men depart from evil, shake off sloth, and preserve themselves from iniquity. He that will keep his heart must eat and drink with fear, rejoice with fear, and pass the whole time of his soul-journey here in fear.

All this is little enough to keep the heart from sin. 6. It includes the realizing of God's presence with us and setting the Lord always before us. This the people have found a powerful means of keeping their heart upright and awing them from sin.

When the eye of our faith is fixed upon the eye of God's omniscience, we dare not let out our thoughts and affections to vanity. Holy Job doth not suffer his heart to yield to an impure vain thought, and what was it that moved him to so great circumspection?

He tells us, does not he see my ways and count all my steps? In such particulars as these do gracious souls express the care they have of their hearts. They are careful to prevent the breaking loose of the corruptions in time of temptation, careful to preserve the sweetness and comfort they have got from God in any duty.

This is a work, and of all works in religion it is the most difficult, constant, and important work. 1. It is the hardest work. Heart work is hard work indeed. To shuffle over religious duties with a loose and heedless spirit will cost no great pains, but to set thyself before the Lord and tie up thy loose and vain thoughts to a constant and serious attendance upon him, this will cost thee something.

To attain a facility and dexterity of language and prayer, and put thy meaning into apt and decent expressions is easy, but to get thy heart broken for sin while thou art confessing it, melted with free grace while thou art blessing God for it, to be really ashamed and humbled through the apprehensions of God's infinite holiness, and to keep thy heart in this frame, not only in but after duty, will surely cost thee some groans and pains of soul.

To repress the outward acts of sin and compose the external part of your life in a laudable manner is no great matter. Even carnal persons by the force of common principles can do this, but to kill the root of corruption within, to set up and keep up an holy government over your thought, to have all things lie straight and orderly in the heart, this is not easy.

2. It is a constant work. The keeping of the heart is a work that is never done till life is ended. There is no time or condition in the life of a Christian which will suffer an intermission of this work.

It is in keeping watch over our hearts that it is with keeping up Moses' hands while Israel and Amalek were fighting. No sooner do the hands of Moses grow heavy and sink down than Amalek prevails, intermitting the watch over their own hearts, but for a few minutes cost David and Peter many a sad day and night.

3. It is the most important business of a Christian's life. Without this we are but formalists in religion. All our professions, gifts, and duties signify nothing. My son, give me thine heart, is God's request.

God is pleased to call that a gift, which is indeed a debt. He will put this honor upon the creature to receive it from him in the way of a gift, but if this be not given him, he regards not whatever else you bring to him.

There is only so much of worth in what we do as there is of heart in it. Concerning the hearts, God seems to say, is Joseph of Benjamin, if you bring not Benjamin with you, you shall not see my face. Among the heathen, when the beast was cut up for sacrifice, the first thing the priest looked upon was the heart, and if that was unsound and worthless, the sacrifice was rejected.

God rejects all duties, how glorious soever in other respects, which are offered him without the heart. He that performs duty without the heart, that is heedlessly, is no more accepted with God than he that performs it with a double heart, that is hypocritically.

Thus, I have briefly considered what the keeping of the heart supposes and imports. I perceive, secondly, to assign some reasons why Christians must make this a great business of their lives. The importance and necessity of making this a great business will manifestly appear from several considerations.

The Glory of God and the Sincerity of Profession

1. The glory of God is much concerned. Heart evils are very provoking evils to the Lord. The schools correctly observe that outward sins are sins of great infamy, but that the heart sins are sins of deeper guilt.

How severely has the great God declared his wrath from heaven against heart wickedness! The crime for which the old world stands indicted is heart wickedness. God saw that every imagination of their hearts was only evil, in fact continually, for which he sent the most dreadful judgments that were ever inflicted since time began.

We find not their murders, adulteries, blasphemies, though they were defiled with these, particularly alleged against them, but the evils of their hearts. That by which God was so provoked as to give up his peculiar inheritance into the enemy's hand was the evil of their hearts.

O Jerusalem, wash thine heart from wickedness, that thou mayest be saved. How long shall thy vain thoughts lodge within thee? Of the wickedness and vanity of their thoughts God took particular notice, and because of this the Chaldeans must come upon them as a lion from his thicket and tear them to pieces.

For the sin of thoughts it was that God threw down the fallen angels from heaven, and still keeps them in everlasting change, to the judgment of the great day, by which expression is not obscurely intimated some extraordinary judgment to which they are reserved.

As prisoners that of most irons laid upon them may be supposed to be the greatest malefactors. And what was their sin? Spiritual wickedness. Merely heart evils are so provoken to God that for them he rejects with indignation all the duties of some men perform.

He that kills an ox is as if he slew a man. He that sacrifices a lamb is as if he cut off a dog's neck. He that offers an oblation is as if he offered swine's blood. He that burns incense is as if he blessed an idol.

And what words could the abhorrence of a creature's actions be more fully expressed by the Holy God? Murder and idolatry are not more vile in his account than their sacrifices, though materially such as himself appointed.

And what made their sacrifices so vile? The following words inform us that their soul delighted in their abominations. Such is the vileness of men's heart sins that the Scriptures sometimes intimate the difficulty of pardon for them.

The heart of Simon Magus was not right. He had base thoughts of God and of the things of God. The apostle bade him repent and pray, if perhaps the thoughts of his heart might be forgiven him. Oh, then never slight heart evils, for by these God is highly wronged and provoked.

For this reason let every Christian keep his heart with all diligence. 2. The sincerity of our profession much depends upon the care we exercise in keeping our hearts. Most certainly that man who is careless of the frame of his heart is but a hypocrite in his profession, however eminent he be in the externals of religion.

We have a striking instance of this in the history of Jehu. But Jehu took no heed to walk in the ways of the Lord God of Israel with his heart. The context gives an account of the great service performed by Jehu against the house of Ahab and Baal, and also of the great temporal reward given him by God for that service, even that his children to the fourth generation should sit upon the throne of Israel.

Yet in these words Jehu is censured as a hypocrite, though God approved and rewarded the work, yet he abhorred and rejected the person that did it, as hypocritical. Wherein lay the hypocrisy of Jehu? In this he took no heed to walk in the ways of the Lord with his heart.

That is, he did all insincerely and for selfish ends, and though the work he did was materially good, yet he, not purging his heart from those unworthy selfish designs and doing it, was a hypocrite. And though Simon Magus appeared such a person that the apostle could not regularly reject him, yet his hypocrisy was quickly discovered.

Though he professed piety and associated himself with the saints, he was a stranger to the mortification of heart sins. Thy heart is not right with God. It is true there is great difference between Christians themselves and their diligence and dexterity about heart work.

Some are more conversant with and more successful in it than others, but he that takes no heed to his heart, that is not careful to order it aright before God, is but a hypocrite. And they come unto thee as a people cometh, and they sit before thee as my people, and I hear thy words, but they will not do them.

For with their mouth they show much love, but their heart goeth after their covetousness. Here was a company of formal hypocrites, as is evident from that expression, as my people, like them, but not of them.

And what made them so? Their outside was fair, here were reverent postures, high professions, much seeming delight in ordinances. You are to them as a lovely song, yea, but for all that, they kept not their hearts with God in those duties.

Their hearts were commanded by their lusts, they went after their covetousness. Had they kept their hearts with God, all had been well, but not regarding which way their hearts went in duty, there lay the essence of their hypocrisy.

If any upright soul should hence infer, I am a hypocrite too, for many times my heart departs from God in duty. Do what I can, yet I cannot hold it close with God. I answer, the very objection carries in it its own solution.

You say, do what I can, yet I cannot keep my heart with God. Soul, if you do what you can, you have the blessing of an upright, though God sees good to exercise thee under the affliction of a discomposed heart.

There still remains some wildness in the thoughts and fancies of the best to humble them. But if you find a care before to prevent them, an opposition against them when they come, and grief and sorrow afterward, you find enough to clear you from the charge of reigning hypocrisy.

This precaution is seen partly in laying up the word in your heart to prevent them. Your word have I hid in my heart, and I might not sin against you. Partly in your endeavors to engage your heart to God, and partly in begging, preventing grace from God in your commencement of duty.

It is a good sign to exercise such precaution, and it is an evidence of uprightness to oppose these sins in their first rise. I hate vain thoughts. The spirit lusteth against the flesh. Your grief also discovers the uprightness of your heart.

If with Hezekiah you are humbled for the evils of your heart, you have no reason from those disorders to question the integrity of it, but to allow sin to lodge quietly in the heart, to let your heart habitually and without control wander from God, is a sad, a dangerous symptom indeed.

The Beauty of Holy Conduct

3. The beauty of our conversation arises from the heavenly frame of our spirits. There is a spiritual luster and beauty in the conversation of saints. The righteous is more excellent than his neighbor.

Saints shine as the lights of the world, but whatever luster and beauty is in their lives comes from the excellency of their spirits, as the candle within puts luster upon the lantern in which it shines.

It is impossible that a disordered and neglected heart should ever produce well-ordered conversation, and since, as the text observes, the issues or streams of life flow out of the heart as a fountain, it must follow that such as the heart is, the life will be.

So, in 1 Peter 2 .12, abstain from fleshly lusts, having your conversation honest, or beautiful, as the Greek word imports. So Isaiah 55 .7, Let the wicked forsake his way, and the unrighteous man his thoughts.

His way denotes the course of his life, his thoughts the frame of his heart. And therefore, since the course of his life flows from his thoughts, or the frame of his heart, both, or neither, will be forsaken.

The heart is the source of all actions. These actions are virtually and radically contained in our thoughts. These thoughts, being at once made up into affections, are quickly made out into suitable actions.

If the heart be wicked, then, as Christ says, out of the heart proceed evil thoughts, murders, and so on. Mark the order, first wanton or revengeful thoughts, then unclean or murderous practices. And if the heart be holy, then it is as with David.

My heart is indicting a good matter. I speak of the things which I have made, touching the king. My tongue is as the pen of a ready writer. Here is a life richly beautified with good works, some ready made.

I will speak of the things which I have made, others making my heart is indicting. Both proceed from the heavenly frame of his heart. Put the heart in frame, and the life will quickly discover that it is so.

It is not very difficult to discern by the performances and converse of Christians what frames their spirits are in. Take a Christian in a good frame, and how serious, heavenly, and profitable will his conversation and religious exercises be.

What a lovely companion is he during the continuance of it. It would do anyone's heart good to be with him at such a time. The mouth of the righteous speaks wisdom, and his tongue talks of judgment. The law of God is in his heart.

When the heart is up with God, and full of God, how dexterously will he insinuate spiritual discourse, improving every occasion and advantage to some heavenly purpose. Few words then run to waste, and what can be the reason that the discourses and duties of many Christians are becoming so frothy and unprofitable?

Their communion both with God and with one another becomes as a dry stock. But this, their hearts are neglected. Surely this must be the reason of it, and it is an evil greatly to be bewailed. Thus the attracting beauty that was likely to shine from the conversation of the saints upon the faces and consciences of the world, which if it did not allure and bring them in love with the ways of God, at least left a testimony in their consciences of the excellency of those men and of their ways, is in a great measure lost to the unspeakable detriment of religion.

Time was, when Christians conducted in such a manner that the world stood gazing at them. Their life and language were of a different strain from those of others. Their tongues discovered them to be Galileans wherever they came.

But now, since vain speculations and fruitless controversies have so much obtained in hard work, practical godliness is so much neglected among professors. The case is sadly altered. Their discourses become like other men's.

If they come among you now, they may hear every man speak in his own language. And I have little hope to see this evil redressed and the credit of religion repaired till Christians do their first works, till they apply again to heart work.

When the salt of heavenly mindedness is cast into the spring, the streams will run more clear and more sweet. 4. The comfort of our souls much depends upon the keeping of our hearts. For he that is negligent in attending to his own heart is ordinarily a great stranger to assurance and the comforts following from it.

Assurance Through Self-Examination and Grace

Indeed, if the antinomian doctrine were true, which teaches you to reject all marks and signs for the trial of your condition, telling you that it is the Spirit that immediately assures you by witnessing your adoption directly without them, then you might be careless of your hearts, yea strangers to them, and yet no strangers to comfort.

But since both Scripture and experience confute this, I hope you will never look for comfort in this unscriptural way. I don't deny that it is the work and office of the Spirit to assure you, yet I confidently affirm that if ever you attain assurance in the ordinary way in which God dispenses it, you must take pains with your own hearts.

You may expect your comforts upon easier terms, but I am mistaken if ever you enjoy them upon any other. Give all diligence, prove yourselves, this is the scriptural method. A distinguished writer in his treatise on the covenant tells us that he knew a Christian who, in the infancy of his Christianity, so vehemently panted after the infallible assurance of God's love, that for a long time together he earnestly desired some voice from heaven.

Yea, sometimes walking in the solitary fields, earnestly desired some miraculous voice from the trees and stones there. This, after many desires and longings, was denied. But in time a better was afforded in the ordinary way of searching the word and his own heart.

In instance of the like nature, another learned person gives us, of one that was driven by temptation upon the very borders of despair. At last being sweetly settled and assured, one asked him how he attained it.

He answered, Not by any extraordinary revelation, but by subjecting my understanding to the scriptures and comparing my heart with them. The Spirit indeed assures by witnessing our adoption, and he witnesses in two ways.

One way is objectively, that is, by producing those graces in our souls which are the conditions of the promise. And so the Spirit and his graces in us are all one. The Spirit of God dwelling in us is a mark of our adoption.

Now the Spirit can be discerned not in his essence, but in his operations. And to discern these is to discern the Spirit. And how these can be discerned without serious searching and diligent watching of the heart I cannot imagine.

The other way of the Spirit's witnessing is effectively, that is, by irradiating the soul with the grace-discovering light shining upon his own work. And this, in order of nature, follows a former work.

He first infuses a grace, and then opens the eye of the soul to see it. Now since the heart is a subject of that infused grace, even this way of the Spirit's witnessing includes the necessity of carefully keeping our own hearts.

For first, a neglected heart is so confused and dark that the little grace which is in it is not ordinarily discernible. The most accurate and laborious Christians sometimes find it difficult to discover the pure and genuine workings of the Spirit in their hearts.

How then shall the Christian who is comparatively negligent about heart work be ever able to discover grace? Sincerity, which is the thing sought, lies in the heart like a small piece of gold on the bottom of a river.

He that would find it must wait till the water is clear, and then he will see it sparkling at the bottom. That the heart may be clear and settled, how much pains in watching, care, and diligence are requisite.

2. God does not usually indulge negligent souls with the comforts of assurance. He will not so much as seem to patronize loss and carelessness. He will give assurance, but it shall be in His own way. His command has united our care and comfort together.

Those are mistaken who think that assurance may be obtained without labor. How many solitary hours have the people of God spent in heart examination? How many times have they looked into the Word and been into their hearts?

Sometimes they thought they discovered sincerity, and were even ready to draw forth a triumphant conclusion of assurance. Then comes a doubt that they cannot resolve, and destroys it all. Many hopes and fears, doubtings and reasonings they have had in their own breasts before they arrived at a comfortable settlement.

But suppose it possible for a careless Christian to attain assurance, yet it is impossible for him long to retain it. For it is a thousand and one if those hearts are filled with the joys of assurance.

Long retain those joys, unless extraordinary care be used. A little pride, vanity, or carelessness will dash to pieces all that for which they have been a long time laboring and many a weary duty. Since then, the joy of our life, the comforts of our souls, rises and falls with our diligence in this work.

Keep your heart with all diligence. 5. The improvement of our graces depends on the keeping of our hearts. I never knew grace to thrive in a careless soul. The habits and roots of grace are planted in the heart, and the deeper they are rooted there, the more flourishing grace is.

In Ephesians 3 .17 we read of being rooted in grace. Grace in the heart is a root of every gracious word in the mouth, and of every holy work in the hand. It is true, Christ is the root of a Christian, but Christ is the originating root, and grace a root originated, planted, and influenced by Christ.

Accordingly, as this thrives under divine influences, the acts of grace are more or less fruitful or vigorous. Now in a heart not kept with care and diligence, these fruit-defying influences are stopped and cut off, multitudes of vanities break in upon it, and devour its strength.
