|Repentance is a U-turn|
What is a good Christian? Some would say it is a person who does everything exactly the way Christ taught—someone who keeps all the commandments perfectly. But we would never say that a good body is one that is never hurt or in which nothing ever goes wrong. There isn’t such a thing. Instead a good body is one that heals rapidly, one that resists illness so that the person doesn’t get sick as often as others, one that when bruised or cut mends fast and well.
Likewise a good Christian is not someone who never does anything wrong. Good Christians turn back to Christ the moment it is discovered they are off course. Good Christians repent well and fast not because they reason that it is the right thing to do or because they are trying to please those around them but because the Light of Christ within them leads them to do it. It is just who they are.
As C. S. Lewis said, a good Christian “does not think God will love us because we are good but that God will make us good because He loves us just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it.”
