1 John 4:1-6
Beloved, 1do not believe every spirit, but 2test the spirits to see whether they are from God, for 3many 4false prophets 5have gone out into the world.
By this you know the Spirit of God: 6every spirit that confesses that 7Jesus Christ has come in the flesh is from God,
and every spirit 8that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and 9now is in the world already.
Little children, you are from God and have overcome them, for 10he who is in you is greater than 11he who is in the world.
12They are from the world; therefore they speak from the world, and 13the world listens to them.
We are from God. 14Whoever knows God listens to us; whoever is not from God does not listen to us. By this we know 15the Spirit of truth and 16the spirit of error.
