The Lordship of Christ over all of a Christian's life is an assumption
basic to Christianity. The acknowledgement of his lordship in psychol
ogy is especially problematic today because of the pervasive naturalis
m and neo-positivism of modern psychology. Nevertheless, an understand
ing of the kingdom concept in Scripture suggests that Christians are i
nevitably called to work towards the expression of Christ's lordship i
n psychology. This occurs as the Christian pursues psychological knowl
edge and practice before God, aware that all true truth about human na
ture is an expression of God's mind, that sin and finitude limit one's
ability to grasp the truth, that the Scriptures are needed to properl
y interpret human nature, and that kingdom activity involves a faithfu
l response to Christ's lordship in one's work with others and one's kn
owing of human nature.
