Test the Spirits
4 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. 2 This is how you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is from God, 3 and every spirit that does not confess that Jesus Christ has come in the flesh is not from God. This is the spirit of the antichrist, which you have heard is coming and is already in the world.
4 You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world. 5 They are of the world, and therefore they speak from the world, and the world listens to them. 6 We are of God, and whoever knows God listens to us. Whoever is not of God does not listen to us. This is how we know the spirit of truth and the spirit of error.
