Thematic Bible: What to try

Beloved, believe not every spirit, but try the spirits, whether they are of God; because many false prophets have gone forth into the world. In this ye know the Spirit of God: every spirit that confesses that Jesus Christ hath come in flesh is of God; and every spirit that confesses not Jesus is not of God; and this is the spirit of the Anti-Christ, of which ye have heard that it is coming, and now it is in the world already.
