'The gospel is not just the ABC's but the A to Z of the Christian life. It is inaccurate to think the gospel is what saves non-Christians, and then Christians mature by trying hard to live accordiung to biblical principles. It is more accurate to say that we are saved by believing the gospel, and then are are transformed in every part of our minds, hearts, and lives by believing the gospel more and more deeply as life goes on.'
Timothy Keller, Center Church, p.48.
