As then the Christian builds his view of man, he does so unashamedly on the basis of the Christian story. This story is the story of the covenant. Man was created as a covenant-keeper, but he soon became a covenant-breaker. When we say he became a covenant-breaker, we mean by that that all men after Adam through the fall of Adam, the first man, came into the world as covenant-breakers (Rom 5:12). Here human choice is so significant that the action of the first man colors the nature of the actions of all later men. All later men are under the wrath and curse of God because of Adam’s rejection of the word of God’s love and command. And they daily add to their sinfulness by their constantly renewed disobedience. But then come the glad tidings of the grace of God in Christ. He who thought it not robbery to be called equal with God because he was God humbled himself to the death, even the death of the cross. And he who knew no sin was made sin for us that we might be made the righteousness of God in him.
