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 LutherFor from the error of not knowing, or understanding, what sin is, there necessarily arises another error, that people cannot know or understand what grace is.
Martin LutherLet us not flutter too high, but remain by the manger and the swaddling clothes of Christ, 'in whom dwelleth all the fullness of the Godhead bodily.'
Martin Luther
