1 John 4:1-3

Complete Jewish Bible

4 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. ² 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, ³ 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!
