Christian Science teaches that God is Mind. Since God is All, then Mind is All, and there can be no other mind. This is the truth, a divine fact. However, we must deal with the belief that there is a material creation, as described in the allegory in the second chapter of Genesis. From the acceptance of the false belief of a material creation comes the equally false conclusion that there is a mind apart from God.
Mortal mind claims to be something which it is not. It claims that it has intelligence, that there is substance in matter, that evil is as powerful as good, and that sin and disease, accidents and calamities, are inevitable. As long as one concedes that he has a mind of his own, he subjects himself to the limitations and abuses of the carnal mind and seems to suffer in consequence. When he recognizes man's dominion by acknowledging that God is the only Mind and therefore the only Mind that he has, he finds that there is in reality no mortal mind that can use or abuse him.
Christ Jesus was accused by the Pharisees of being in league with Satan when he healed a man who was blind and dumb. Jesus replied (Matt. 12:26–29): "If Satan cast out Satan, he is divided against himself; how shall then his kingdom stand? . . . But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you. Or else how can one enter into a strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house."
