The Bible warns us about false prophets and teachers who attempt to lead Gods people astray from the truth. Today there are more heresies, false cults and teachers than ever before. How can we protect ourselves and our churches from these destructive teachings and cults? And how can we discern whether or not something is from God? This book presents basic biblical principles for checking teachings, teachers and spiritual movements against scripture. It takes a closer look at some major issues within cult groups and in false doctrines, and presents clear teaching from the Holy Bible, comparing it with distortions of the truth that are found in dangerous spiritual environments.
