Christian Psychology is based on the knowledge of the Lord Jesus Christ, not on the knowledge of ourselves. It is not the study of human nature analysed and expounded, but the study of the new life that is born in us through the Redemption of our Lord, and the only Standard of that new life is our Lord Himself; He is formed in us by regeneration (Galatians i. 15–16). We are apt to start with the way we are made naturally and to transfer our reasonings on that to Jesus Christ, inferring that to understand ourselves is to understand Him. In Christian Psychology we have not to introspect as we do in natural psychology; we have to accept the revelations given to us in and through our Lord Jesus Christ; that is, we must take all our bearings from the Son of God, not from our natural wits. We have not to study and understand ourselves; but to understand the manifestation in us of the life of the Son of God Who became Son of Man, the Lord Jesus Christ.

According to the Bible, there are only two Men—Adam and Jesus Christ, and God deals with them as the representatives of the human race, not as individuals. All the members of the human race are grouped round these two Men. The first Adam is called ‘the son of God’; the last Adam is the Son of God, and we are made sons of God by the last Adam. The Christian is neither Adam nor Jesus Christ, the Christian is a new man in Christ Jesus. The first Adam and the last Adam are the only two Men according to God’s norm, and they both came into this world direct from the hand of God.
