1 John 4:1-3

RYLT(i) 1 Beloved, every spirit believe not, but prove the spirits, if of God they are, because many false prophets have gone forth to the world; 2 in this know you the Spirit of God; every spirit that does confess Jesus Christ in the flesh having come, of God it is, 3 and every spirit that does not confess Jesus Christ in the flesh having come, of God it is not; and this is that of the antichrist, which you heard that it does come, and now in the world it is already.
