God has surely promised His grace to the humbled: that is, to those who mourn over and despair of themselves. But a man cannot be thoroughly humbled till he realizes that his salvation is utterly beyond his own powers, counsels, efforts, will and works, and depends absolutely on the will, counsel, pleasure and work of Another -- God alone.
Martin LutherLook to it that you do not try to do all of it, do not try to do too much, lest your spirit grow weary. Besides, a good prayer mustn't be too long. Do not draw it out. Prayer ought to be frequent and fervent.
Martin LutherThe will of man without the grace of God is not free at all, but is the permanent prisoner and bondslave of evil since it cannot turn itself to good.
Martin LutherWe come to the New Testament, where again a host of imperative verbs is mustered in support of that miserable bondage of free-choice, and the aid of carnal Reason with her inferences and similes is called in, just as in a picture or a dream you might see the King of the flies with his lances of straw and shields of hay arrayed against a real and regular army of seasoned human troops. That is how the human dreams of Diatribe go to war with the battalions of divine words.
Martin Luther
