“To deny God as ultimate means to affirm man as ultimate. To make nature the container of God is finally to make man God's container. Whenever Christian philosophy has had any other starting point than the self-contained God, it has led, despite its protestations, to a man-contained God. In the morning, it finds itself in bed with Leah.
…The basic issue, therefore, has not changed since Eden. The temptation of man is "To be as God," knowing, that is, determining for himself what shall be good and what shall be evil. Man establishes his own law and decrees his own righteousness and is not bound to a point of reference beyond himself. This is the original sin of man, the lust to be as God, and this is the constant drive of his being from which even the redeemed are not free. Man sees himself not as creature but as a god, not as dependent but as an independent and autonomous being. Not even the most devout are free in this life from traces of this rebellion…”
