1 John 4:1-6 Christian Standard Bible (CSB)
The Spirit of Truth and the Spirit of Error
4 Dear friends, do not believe every spirit, but test the spirits to see if 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 but every spirit that does not confess Jesus[a] is not from God. This is the spirit of the antichrist, which you have heard is coming; even now it is already in the world.
4 You are from God, little children, and you have conquered them, because the one who is in you is greater than the one who is in the world. 5 They are from the world. Therefore what they say is from the world, and the world listens to them. 6 We are from God. Anyone who knows God listens to us; anyone who is not from God does not listen to us. This is how we know the Spirit of truth and the spirit of deception.
