The Spirit of God and the Spirit of Antichrist
41 Beloved, believe not every spirit, but prove the spirits, whether they are of God; because many false prophets are gone out into the world. 2 Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God: 3 and every spirit that confesseth not Jesus is not of God: and this is the [spirit] of the antichrist, whereof ye have heard that it cometh; and now it is in the world already.
4 Ye are of God, [my] little children, and have overcome them: because greater is he that is in you than he that is in the world. 5 They are of the world: therefore speak they [as] of the world, and the world heareth them. 6 We are of God: he that knoweth God heareth us; he who is not of God heareth us not. By this we know the spirit of truth, and the spirit of error.
