“Because man is born a rebel, he is unaware that he is one. His constant assertion of self, as far as he thinks of it at all, appears to him a perfectly normal thing. He is willing to share himself, sometimes even to sacrifice himself for a desired end, but never to dethrone himself.
No matter how far down the scale of social acceptance he may slide, he is still in his own eyes a king on a throne, and no one, not even God, can take that throne from him. Sin has many manifestations but its essence is one. A moral being, created to worship before the throne of God, sits on the throne of his own selfhood and from that elevated position declares, ‘I AM.’ That is sin in its concentrated essence.”
