In the New Testament, we are warned about false human teachers, but we are also cautioned against deceiving spirits. Jesus warns us about false prophets and false messiahs in Matthew 24:24 and Mark 13:22. Colossians 2:8-10 instructs us to reject corrupt theology based on the philosophies of worldly spiritual teachings. 1 John 4:1-4 instructs us to test the spirits and reject those that lead people away from the teachings of Jesus and his apostles. Galatians 1:8 warns against the false gospel preached by anyone, including fallen angels. 2 Corinthians 11:13-15 states that false teachers pretending to be godly are like Satan, who masquerades as an angel of light. Additionally, Colossians 2:18 states that angels shouldn’t be worshiped or prayed to.
