How God Called Me to a World-Wide Ministry — Oswald J. Smith
In this sermon, the speaker addresses the problem of a plenteous harvest but few laborers, which he believes is a problem in both his time and ours. He emphasizes the importance of spreading the gospel to all nations and all people, as commanded by God. The speaker encourages the audience to either go themselves or support others in spreading the gospel. He shares a personal story of raising funds to support missionaries and how the congregation's generosity led to an increase in the number of missionaries sent out. The sermon concludes with the message that the work of evangelizing the world is ongoing and that everyone has a role to play in fulfilling God's plan.
