God says, "A new heart also will I give you, and a new spirit will I put within you," thus signifying that the whole mind must be embraced in the regeneration. There must be perfect co-operation of the three phases of mind in order to produce the perfect man. "I, Jehovah, search the mind, I try the heart, even to give every man according to his ways, according to the fruit of his doings." "Purify your hearts, ye double-minded," says James. We purify our heart when we turn conscious attention within and the pure ideas of the superconscious mind come forth to meet our call. "He that is joined unto the Lord is one spirit." When we seek the superconsciousness and make conscious connection with it we harmonize all the forces of mind and body; we lift up the subconscious until a complete, conscious unification of the three phases of mind is affected and we become established "in singleness of . . . heart." We can say with the Psalmist, "His heart is fixed, trusting in Jehovah." We fear nothing, for we know that we draw on the divine ideas in God-Mind and that they all are good.
