Thematic Bible: What to try

BELOVED, believe not every spirit, but prove the spirits whether they are of God; for many false prophets have gone out into the world. By this you know the Spirit of God; every spirit which confesses that Jesus Christ has come in the flesh is of God, and every spirit which does not confess Jesus is not of God. And this is the [spirit] of anti-christ, of which you have heard that he is coming, and he is now in the world already.
