Thematic Bible: What to try

Beloved, believe not every spirit, but try the spirits, whether they are of God, because many false prophets are gone out into the world. Hereby ye know the spirit of God: every spirit which confesseth Jesus Christ come in the flesh, is of God. And every spirit which confesseth not Jesus Christ come in the flesh, is not of God: and this is that spirit of Antichrist, whereof ye have heard that it should come; and now already it is in the world.
