1 John 4:1-6

1 Dearly beloved, believe not every spirit, but try the spirits if they be of God: because many false prophets are gone out into the world.

2 By this is the spirit of God known. Every spirit which confesseth that Jesus Christ is come in the flesh is of God:

3 And every spirit that dissolveth Jesus is not of God. And this is Antichrist, of whom you have heard that he cometh: and he is now already in the world.

4 You are of God, little children, and have overcome him. Because greater is he that is in you, than he that is in the world.

5 They are of the world. Therefore of the world they speak: and the world heareth them.

6 We are of God. He that knoweth God heareth us. He that is not of God heareth us not. By this we know the spirit of truth and the spirit of error.
