[Inaccurate assumptions of psychology include] human nature is basically good, people have the answers to their problems inside them, the key to understanding and correcting a person’s attitudes and actions lies somewhere in his past, individuals’ problems are the result of what someone else has done to them, human problems can be purely psychological in nature – unrelated to any spiritual or physical condition, deep-seated problems can be solved only by professional counselors using therapy, Scripture, prayer, and the Holy Spirit are inadequate and simplistic resources for solving certain types of problems.
