The fundamental proposition to which this article is addressed is that the process, posited by cognitive theorists, to underlie change and growth is identical to the scriptural process of sanctification. The essential tenets of cognitive theory are presented after a brief introduction. The veracity of these principles is then substantiated by an examination of relevant empirical research studies. Next, the methodology of cognitive therapy a la Meichenbaum is set forth. This particular conceptualization of the therapeutic process is subsequently described as forming a model of the sanctification process in which the processes in these two spheres (the psychological and theological) are seen as the same, but the contents are seen as different. The role of the will is evaluated in the context of the change process followed, finally, by a Christian rationale of cognitive therapy.
