As long as a man is persuaded that he can make even the smallest contribution to his salvation, he remains self-confident and does not utterly despair of himself, and so is not humbled before God. Such a man plans out for himself a position, an occasion, a work, which shall bring him final salvation, but which will not.
Martin LutherOur most merciful Father, seeing us to be oppressed and overwhelmed with the curse of the law . . . sent his only Son into the world and laid upon him all the sins of all men, saying, 'You be Peter that denier, Paul that persecutor, blasphemer and cruel oppressor, David that adulterer, that sinner who ate the apple in Paradise, that thief who hung upon the cross, and briefly, you be the person who has committed the sins of all men. See therefore that you pay and satisfy for them.'
Martin LutherEverything is from God himself, both commandment and fulfillment. He alone commands; he alone fulfills.
Martin Luther
