The Gospel is Not Just the ABC’s but the A-to-Z of the Christian life.

Over a series of posts, I’m writing about the sentences that have changed my life (part 1). Here’s the second: The gospel is not just the ABC’s but the A-to-Z of the Christian life.

The gospel

I’m not exactly sure who first coined this sentence — my guess would be either Dick Kauffman or Tim Keller — but I first came across it in a study called “Gospel and Heart,” that Kauffman and Keller created together. Regardless, this sentence has been a terrific summary of what it means to be “gospel-centered.”

This idea was and is so influential to me because I often thought of the gospel as something you moved on from as you matured as a Christian (the ABC’s). It was important–critically important–for salvation. But once you had salvation, I assumed you really just needed a better understanding of biblical principles.

I actually remember talking with a pastor friend who was telling me how he wanted to have the gospel be in every sermon and I thought, “How boring.” How wrong I was.

The flaw in my thinking, however, was not realizing that all biblical principles are connected to the gospel. Additionally, a robust understanding of the gospel provides the power to obey biblical principles. The gospel really is the A-to-Z of the Christian life.

I’ve now come to see the gospel as a precious jewel that can be turned and examined from countless angles, all with a fresh perspective on the majesty of God.

I’ve come to believe that the gospel can be in every sermon I preach in a way that is fresh and interesting.

Most importantly, I’ve seen the gospel continue to change and grow me in deeper ways the longer I follow Jesus.

  1. Hey Luke,

    I’m confused about your admission that a flaw in your thinking was “all biblical principles are connected to the gospel.”

    It doesn’t sound congruent to the rest of your thoughts. Did you mean “aren’t?”
