"God Himself is the nearest to hand, as the absolutely simple must be, and at the same time the most distant, as the absolutely simple must also be. God Himself is the irresolvable and at the same time that which fills and embraces everything else. God Himself in His being for Himself is the one being which stands in need of nothing else and at the same time the one being by which every thing else came into being and exists. God Himself is the beginning in which everything begins, with which we must and can always begin with confidence and without need of excuse. And at the same time He is the end in which everything legitimately and necessarily ends, with which we must end with confidence and without need of excuse. God Himself is simple, so simple that in all His glory He can be near to the simplest perception and also laugh at the most profound or acute thinking so simple that He reduces everyone to silence, and then allows and requires everyone boldly to make Him the object of their thought and speech. He is so simple that to think and speak correctly of Him and to live correctly before Him does not in fact require any special human complexities or for that matter any special human simplicities, so that occasionally and according to our need He may permit and require both human complexity and human simplicity, and occasionally they may both be forbidden us..."

“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.”
