Years ago my wife and I were part of a congregation that fell into the depths of spiritual deception and became cultic. The events of those days led to the ruin of many lives. Most shocking was the number of students from evangelical backgrounds who were so easily deceived. How did this happen? What were the spiritual principles involved that led to such a great tragedy? It is my conviction that the account of this congregation and the review of the principles involved in their deception will prevent the same thing from occurring elsewhere. May those who read this learn to guard themselves against the Dynamics of Spiritual Deception.
