1 John 4:1-6 WYC

1 Most dear brethren, do not ye believe to each spirit, but prove ye the spirits, if they be of God; for many false prophets went out into the world.
2 In this thing the Spirit of God is known; each spirit that acknowledgeth that Jesus Christ hath come in flesh, is of God;
3 and each spirit that undoeth Jesus, is not of God. And this is antichrist, of whom ye have heard, that he cometh; and right now he is in the world.
4 Ye, little sons, be of God, and ye have overcome him; for he that is in you is more, than he that is in the world.
5 They be of the world, therefore they speak of the world, and the world heareth them.
6 We be of God; he that knoweth God, heareth us; he that is not of God, heareth not us. In this thing we know the spirit of truth, and the spirit of error.
