The Bible warns us about people who are false prophets.

2 Peter 2:1-3 King James Version

2 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.

² And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.

³ And through covetousness shall they with feigned words make merchandise of you: whose judgment now of a long time lingereth not, and their damnation slumbereth not.

1 John 4:1-Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.

Matthew 7:15 – Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.

Deuteronomy 18:20 – But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.

2 Corinthians 11:13-For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
