what does the bible say?
False teachers are those whose message does not align with God’s Word, and Scripture commands believers to recognize them by testing all teaching against truth (Matthew 7:15–16; Acts 17:11). The Bible shows that false teachers are to be dealt with strongly, confronted with the truth, and exposed for what they are. The Old Testament contains dire warnings about those who falsely claim to speak for God (Deuteronomy 13:1-3). It was a capital crime to do so (Deuteronomy 18:20), showing the seriousness of the sin. The New Testament indicates that we are not to have anything to do with those who teach lies about God (Romans 16:17; 2 John 1:7-11). Jesus also warned about false prophets (Matthew 7:15). His followers should observe not only what people say but the fruits of those who claim to be Christian to see if their behavior aligns with that claim. We can identify and respond to false prophets when we know and stand firm on God's Word (2 Timothy 3:16-17; Acts 17:11), which is the best protection against spiritual charlatans. Knowing God's Word also helps us to confront them with the truth (Ephesians 5:11). Christians have a responsibility to contend for the truth so His Word won't be twisted and people won't be ensnared by lies (Jude 3-4; cf. 1 Peter 3:15).
