It is inaccurate to think the gospel is what saves non-Christians, and then Christians mature by 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 minds, hearts, and lives by believing the gospel more and more deeply as life goes on.

Timothy KellerIf your fundamental is a man dying on the cross for his enemies, if the very heart of your self-image and your religion is a man praying for his enemies as he died for them, sacrificing for them, loving them - if that sinks into your heart of hearts, it's going to produce the kind of life that the early Christians produced. The most inclusive possible life out of the most exclusive possible claim - and that is this is the truth. But what is the truth? The truth is a God become weak, loving and dying for the people who opposed him, dying forgiving them.
