false prophet

Definition:

A false prophet is a person who wrongly claims that his message comes from God.

The prophecies of false prophets are not usually fulfilled. That is, they do not come true.
False prophets teach messages that partially or totally contradict what the Bible says.
This term could also be translated as “person who falsely claims to be God’s spokesman” or “someone who falsely claims to speak God’s words.”
The New Testament teaches that in the end times there will be many false prophets who will try to deceive people into thinking that they come from God.
