1 John 4:1-6

1Beloved, 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. 2By this you will know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is from God, 3and every spirit that does not confess Jesus1 is not from God. This is the spirit of the antichrist, which you have heard is coming and which is already in the world at this time.

4You, little children, are from God and have overcome them, because greater is He who is in you than he who is in the world. 5They are of the world. That is why they speak from the world’s perspective, and the world listens to them. 6We are from God. Whoever knows God listens to us; whoever is not from God does not listen to us. That is how we know the Spirit2 of truth and the spirit of deception.
