Does it follow from: 'turn ye' that therefore you can turn? Does it follow from "'Love the Lord thy God with all thy heart' (Deut 6.5) that therefore you can love with all your heart? What do arguments of this kind prove, but the 'free-will' does not need the grace of God, but can do all things by its own power....But it does not follow from this that man is converted by his own power, nor do the words say so; they simply say: "if thou wilt turn,telling man what he should do. When he knows it, and sees that he cannot do it, he will ask whence he may find ability to do it..." 164
Martin LutherAlthough the Christian is thus free from all works, he ought in this liberty to empty himself, take upon himself the form of a servant, be made in the likeness of men, be found in human form, and to serve, help and in every way deal with his neighbor as he sees that God through Christ has dealt and still deals with him.
Martin Luther
