Jesus Christ advised his followers: “Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.”—Matthew 7:15. The apostle Paul likewise warned Christians in Thessalonica: “Let no one deceive you in any way, for it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction.”—2 Thessalonians 2:3.
