1 John 4:2-4

Revised Geneva Translation

² By this you shall know the Spirit of God: Every spirit which confesses that Jesus Christ has come in the flesh is of God.

³ And every spirit that does not confess that Jesus Christ has come in the flesh, is not of God. But this is the spirit of Antichrist, of whom you have heard; how that he would come and is now already in this world.

⁴ Little children, you are of God; and have overcome them! For greater is He Who is in you than he who is in this world.
