In Christian theology sin and grace are intrinsically interconnected. Teacher and counselor Mark McMinn believes that Christian counseling, then, must also take account of both human sin and God's grace. For both sin and grace are distorted whenever one is emphasized without the other.

McMinn, noting his own tendencies and the temptation to stereotype different Christian approaches to counseling along this theological divide, aims to help all those preparing for or currently serving in the helping professions. Expounding the proper relationship of sin and grace, McMinn shows how the full truth of the Christian gospel works itself out in the functional, structural and relational domains of an integrative model of psychotherapy.
