1John:4:1-3
bbe@1John:4:1 @My loved ones, do not put your faith in every spirit, but put them to the test, to see if they are from God: because a great number of false prophets have gone out into the world.
bbe@1John:4:2 @By this you may have knowledge of the Spirit of God: every spirit which says that Jesus Christ has come in the flesh is of God:
bbe@1John:4:3 @And every spirit which does not say this is not from God: this is the spirit of Antichrist, of which you have had word; and it is in the world even now.
