Here’s a helpful post from Tim Challies answering the question:
I was hoping for some guidance on something. I am looking for books about being ‘Gospel-Centered.’ I know that is a buzzword nowadays and it is really intriguing to me.

Don’t get me wrong, I love Jesus and Scripture and the Gospel, but I’ve never really heard or really understand the Gospel-Centered.
