The purpose of this paper lies in understanding the grandiose sense of self typically observed in the therapeutic setting of play therapy with children, and providing its therapeutic model for Christian counseling. This paper is based on some example cases of child analysis in which the children’s grandiosity is distinguished. Psychoanalysts views the grandiosity differently based on their own understanding of narcissism and its therapeutic intervention. Kernberg contended that narcissism should be overcome so that the healthy analytic relationship between analyst and patient can be formed. However, Kohut maintained that narcissism in the analytic setting should be accepted and allowed because it is a driving force of human psychological development. Relational psychoanalysis has tried to integrate two different tradition with its own terms, “old object,” and “new object.” “Persuasive God” in the process theology can be a therapeutic model for Christian counseling to integrate two different therapeutic interventions.
