1 Beloued, beleeue not euery spirit, but trie 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: euery spirit that confesseth that Iesus Christ is come in the flesh, is of God.
3 And euery Spirit that confesseth not that Iesus Christ is come in the flesh, is not of God: and this is that spirit of Antichrist, whereof you haue heard, that it should come, and euen now already is it in the world.
4 Ye are of God, little children, and haue ouercome them: because greater is he that is in you, then he that is in the world.
5 They are of the world: therefore speake they of the world, and the world heareth them.
6 We are of God: hee that knoweth God, heareth vs: he that is not of God heareth not vs, hereby know wee the spirit of trueth, and the spirit of errour.
1 Jn 4:1-6
