Bible Verses About False Prophets: Mode of trying and detecting

"If a prophet or someone who gets messages while dreaming arises among you and he gives you a sign or wonder,

and the sign or wonder comes about as he predicted when he said, 'Let's follow other gods, which you have not known; and let us serve them,'

You may be wondering, 'How are we to know if a word has not been spoken by ADONAI?'

When a prophet speaks in the name of ADONAI, and the prediction does not come true -that is, the word is not fulfilled -then ADONAI did not speak that word. The prophet who said it spoke presumptuously; you have nothing to fear from him.

Dear friends, don’t trust every spirit. On the contrary, test the spirits to see whether they are from God; because many false prophets have gone out into the world.

Here is how you recognize the Spirit of God: every spirit which acknowledges that Yeshua the Messiah came as a human being is from God,

and every spirit which does not acknowledge Yeshua is not from God — in fact, this is the spirit of the Anti-Messiah. You have heard that he is coming. Well, he’s here now, in the world already!
