He became what we are that he might make us what he is.
Athanasius

God became man to turn creatures into sons: not simply to produce better men of the old kind but to produce a new kind of man.
C.S. Lewis

The mystery of Christ, that He sunk Himself into our flesh, is beyond all human understanding.
Martin Luther

The Son of God became a man to enable men to become sons of God.
C.S. Lewis

Nowhere is salvation conceived of as a flight from history as in Greek thought; it is always the coming of God to man in history. Man does not ascend to God; God descends to man.
George Eldon Ladd
