Yesterday morning I preached on "Warning Signs of False Religion" from Deuteronomy 13, 18. Church member Chelsea Rowe shared a personal testimony of how she was a Jehovah's Witness until she was 18, and no Christian ever shared the gospel with her while she was knocking on doors.
After the sermon, people approached me with concern for friends and relatives involved in several different cults and world religions.
As I said in the sermon, Deuteronomy chapters 18 and 13 give three tests of false religion: false words, false ways, and false worship. I showed how this applies to Jehovah's Witnesses, Mormons, witchcraft, Islam and other groups. Click on the "comments" below and read the text of the entire sermon in the first comment.
