"When I come before these men I do not have to explain that we are all sinners. They have committed every sin there is. All I have to tell them is that I, too, am a sinner."

“When attempts were later made to speak systematically about God and to describe His nature, men became more talkative. They spoke of God's aseity , His being grounded in Himself; they spoke of God's infinity in space and time, and therefore of God's eternity. And men spoke on the other hand of God's holiness and righteousness, mercifulness and patience. We must be clear that whatever we say of God in such human concepts can never be more than an indication of Him; no such concept can really conceive the nature of God. God is inconceivable.”

“Frederick the Great once asked his personal physician, Dr. Zimmermann, "Can you name me a single proof of the existence of God?" Zimmermann replied, "Your Majesty, the Jews!" By that he meant that if one wanted to ask for a proof of God, for something visible and tangible, that no one could contest, which is unfolded before the eyes of all men, then we should have to turn to the Jews. Quite simply, there they are to the present day. Hundreds of little nations in the Near East... have dissolved and disappeared in the huge sea of nations; this one tiny nation has maintained itself.... If the question of a proof of God is raised, one need merely point to this simple historical fact. For in the person of the Jew there stands before our eyes the witness of God's covenant with Abraham, Isaac, and Jacob, and in that way with us all. Even one who does not understand Holy Scripture can see this reminder.”

“We know that God is He whom we do not know, and that our ignorance is precisely the problem and the source of our knowledge. The Epistle to the Romans is a revelation of the unknown God; God chooses to come to man, not man to God. Even after the revelation man cannot know God, for he is ever the unknown God. In manifesting himself to man he is farther away than before.”

“The power of God can be detected neither in the world of nature nor in the souls of men. It must not be confounded with any high, exalted, force, known or knowable.”
