So the first part of the book kinda lays out like this, the necessity of regeneration, why do we need to be born again, and the sovereignty of regeneration, that is, God is the one who brings about a regeneration, you can't do it, you don't want it, and you can't do it, and then the totality of regeneration, so regeneration as depravity is total, regeneration is total, too, touches everything, doesn't make us perfect, but every part that was broken by the fall, as far as internally, regeneration touches, our thoughts, our will, our affections, and then finally, the longevity of regeneration, and that's an important truth to remember, is like, when you're born again, and this is where we differ from our Presbyterian brothers and sisters, they wouldn't say you're unborn again, but what we say is, it's only those born again who are in the new covenant, and once you enter the new covenant, you can't get out of it, because you've been born again, God's law is written on your heart, your sins have been forgiven, and you know God, and so that's how the first part of the book, and we do a little bit of historical survey, but the catalyst, I guess that's kind of back to your question, the catalyst of the book is just looking around and seeing an anemic Christianity in our day, and a lot of even people who are pastors and leaders in churches, and evangelicalism, and the Southern Baptist Convention, and all those things, they don't really wanna touch this, you know, like everybody, no, like, you know, that man that's living with his girlfriend, and you know, they don't wanna say he's not a Christian, you know, well, he's backslidden, or something like that, and you're like, and look, I know there's a thousand scenarios we could talk about, but the reality is, those who are Christians, true Christians, have been given a new heart.
