We shall be judged according to our works – this is why we are exhorted to do good works. The Bible assuredly knows nothing of those qualms about good works, by which we only try to excuse ourselves and justify our evil works. The Bible never draws the antithesis between faith and good works so sharply as to maintain that good works undermine faith. No, it is evil works rather than good works which hinder and destroy faith. Grace and active obedience are complementary. There is no faith without good works, and no good works apart from faith.
— Dietrich Bonhoeffer, The Cost of Discipleship
