One of the most influential and pivotal books I have ever (yes, ever) read was Bryan Chapell’s Christ-Centered Preaching. This along with some of the writings of Tim Keller (Pastor at Redeemer Pres in NYC), Jerry Bridges, and C. J. Mahaney (to name just a few) awoke me to the centrality of the Gospel in all aspects of life.
Perhaps one of the most eye-opening realizations throughout all of this is that
the gospel is not just for non-Christians, but also for Christians. This means the gospel is not just the A-B-C’s but the A to Z of the Christian life. It is not accurate to think ‘the gospel’ is what saves non-Christians, and then, what matures Christians is trying hard to live according to Biblical principles. It is more accurate to say that we are saved by believing the gospel, and then we are transformed in every part of our mind, heart, and life by believing the gospel more and more deeply as our life goes on. [Keller]
How encouraging, then, to hear Piper reinforce this in the clip below:
