Christian Hedonism changes how we think about conversion. Listen to Matthew 13:44, “The kingdom of heaven is like treasure hidden in a field, which a man found” — finding the kingship of Jesus for your life — “Which a man found and covered up, and then, in his joy, he goes and sells everything he has and buys that field.” That’s a picture of conversion, isn’t it?
I’m sure there are people in this room now who are not Christian — truly, Bible-believing, born-again lovers of Jesus. What does that mean? It means not only believing truth, but finding a treasure. So, evangelism becomes not only persuasion about truth, but pointing to a treasure — a treasure that’s more valuable than anything you have. That’s conversion.
The Holy Spirit does something, and suddenly, Christ is attractive, beautiful, glorious, sufficient, needed, a magnified Savior, and the soul is honoring that by a growing sense of “You’re enough. You satisfy me. All that stuff I’ve been living for, it’s just getting weaker and weaker.” This doesn’t happen all at once.
First Peter describes the new birth, and then if this rascal chapter break would get out of the way at chapter two — just forget chapter breaks, right? They really get in the way, especially between chapter one and two of 1 Peter. Oh my, that’s a bad one. Just get rid of that chapter break, and it goes right into telling you how you move from new birth to growth: “like newborn babes, desire the sincere spiritual milk, that by it, you may grow up into salvation, if indeed you tasted that the Lord is good” (1 Peter 2:1–2). And all that’s relating back to “You were born again, not with perishable seed, but with imperishable, through the living and abiding word of God” (1 Peter 1:23). Shame on you, chapter break.
We have to see what it is to be born, and then to grow, by desiring the milk of the word, which helps you taste and see he’s really good. And that’s how you grow. That’s the fight. So conversion is the discovery of a treasure that is more valuable than anything (Matthew 13:44).
