1 John 4:2-5

2This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God,

3but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.

4You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.

5They are from the world and therefore speak from the viewpoint of the world, and the world listens to them.
