God does more than just influence—he predestines. That’s why all things will work together for the good of the called, and Christ will be the firstborn among many brothers (Rom. 8:29). God is in charge. The outcome is secure. And that, my friends, is a guarantee.

To this day, whenever I stand behind a pulpit and say things like “All true saints will persevere to the end and none will be lost,” I still have to pinch myself. I laugh inwardly and think, What would the 22-year-old me say if he could hear me now?

You see, I wasn’t always a Calvinist.

I was raised a classical Arminian in the Free Will Baptist tradition. As a teenager, I cut my teeth on theologians like F. Leroy Forlines and J. Matthew Pinson, along with older divines like James Arminius and John Wesley. As a 22-year-old man, I believed and taught that grace was always necessary but never irresistible, and that genuine Christians could abandon Christ and forfeit their justified status.

Beneath these beliefs lay a view of the God/man relationship that went like this: humans were created to exist in a loving relationship with God. The nature of that loving relationship requires a free—and undetermined—response on our part. To quote Forlines, I saw God working with man in an “influence-and-response relationship” rather than a “cause-and-effect relationship” (like the Calvinists thought). God could influence us, but he respected our personhood by always leaving the final decision up to us. And God did this, not because he was weak, but because this was how he meant for the relationship to work.

And in case you’re wondering, the difference between a God who influences and a God who causes can be summed up in one word: guarantee. Forlines puts it this way in his book The Quest for Truth:

I think the description of God’s relationship to man that Calvinists would give would be much like my description of influence and response. However, the result is thought to be guaranteed…Any time the result is guaranteed, we are dealing with cause and effect. When the guarantee is gone, Calvinism is gone.

He’s right. I agreed with him then; I agree with him now. I’ve simply changed sides. So what happened? The short answer is I ran up against Romans 8:28–30.

Passionate Preacher, Problem Passage

Romans 8:28–30 is often referred to as “the golden chain of redemption”—so called because of its five “links” of divine foreknowing, predestining, calling, justifying, and glorifying.

As an Arminian, I saw Romans 8:28–30 as a problem passage. Verse 29 was definitely a key prooftext for election-based-on-foreseen-faith. But the rest was difficult. I knew what my preferred commentators said about it, but I’d never been fully satisfied. So I chalked it up to an anomaly. After all, no theological system explains everything perfectly.

Then I started listening to John Piper’s sermons on Romans, and my world was unmade. It was 2004, I was 22, and I had never heard such preaching. His meticulous exposition exposed all the weaknesses I already sensed in my interpretation of the passage, while uncovering some new ones. I can’t say I emerged from those sermons a convinced Calvinist. But my confidence was severely shaken. And eventually I came to realize that Paul’s golden chain, like Calvinism, was very much about a guarantee.
