“I have many people in this city.” – Acts 18:10
This should be a great encouragement in proclaiming the Gospel, since among the people in our communities—the disinterested, the rebellious, the careless—God has an elect people who must be saved. When you take the Word to them, you do so because God has ordained you to be the messenger of life to their souls, and they must receive it, for so the decree of predestination runs. They are as much redeemed by blood as the saints before the eternal throne. They are Christ’s property, and yet perhaps they are lovers of selfish pleasures and haters of holiness; but if Jesus Christ purchased them, He will have them. God is not unfaithful to forget the price that His Son has paid. He will not suffer His substitution to be in any case an ineffectual, dead thing. Tens of thousands of redeemed ones are not regenerated yet, but regenerated they must be; and this is our comfort when we go to them with the quickening Word of God.
– Charles Spurgeon
