A man cannot do good before he is made good.

Why do you rant and brag with such a spate of words, as if you wanted to overwhelm me with a sort of tempest and deluge of oratory-which nevertheless falls with the greater force on your own head, while my ark rides aloft in safety?

I am not permitted to let my love be so merciful as to tolerate and endure false doctrine. When faith and doctrine are concerned and endangered, neither love nor patience are in order....when these are concerned, neither toleration nor mercy are in order, but only anger, dispute, and destruction - to be sure, only with the Word of God as our weapon.

When Jesus Christ utters a word, He opens His mouth so wide that it embraces all Heaven and earth, even though that word be but in a whisper.

God's entire divine nature is wholly and entirely in all creatures, more deeply, more inwardly, more present than the creature is to itself.

Let all your preaching be in the most simple and plainest manner; look not to the prince, but to the plain, simple, gross, unlearned people, of which cloth the prince also himself is made. If I, in my preaching, should have regard to Philip Melancthon and other learned doctors, then should I do but little good. I preach in the simplest manner to the unskillful, and that giveth content to all. Hebrew, Greek and Latin I spare until we learned ones come together.

The law of God cannot be fulfilled by external obedience.
