Beloved, do not believe every spirit, but test the spirits to see whether they are from God. For many false prophets have gone out into the world.
By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God,
and every spirit that does not confess Jesus is not of God, and this is that of the antichrist, which you heard that is coming, and now is already in the world.
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.
They are of the world; because of this they speak from out of the world, and the world listens to them.
We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error.
1 John 4
