". . . . . .There was Peter's own self-strength, self-confidence. 'Lord, with you I am ready to go both to prison and to death.' He later found out how unready, how unprepared, he was for that, but at the time it was a case of self-confidence, and that ground brought his undoing and Satan's power. The self still alive and dominant instead of dead, put to the Cross, is the ground of Satan's power. Not until the soul has been denied and laid down is the power of Satan destroyed and spiritual power established in the life of the child and the servant of God. It is a question of the ground -- whether it is the world or whether it is the self (another word for the flesh) -- that determines how far Satan has power and how far we have spiritual power."
