Most people in the world believe that if there is a God, you relate to God by being good. Most religions are based on that principle, though there are a million different variations on it...But they all have the same logic: If I perform, if I obey, I’m accepted. The gospel of Jesus is not only different from that but diametrically opposed to it: I’m fully accepted in Jesus Christ, and therefore I obey.
Timothy KellerThe main problem in the Christian life is that we have not thought out the deep implications of the gospel, we have not 'used' the gospel in and on all parts of our life.
