1 John 4:4-6

We belong to GOD, my children, and we have overcome the false prophets, because the ONE who is in you is greater than the one who is in the world. They are of the world, and what they have to say is of the world, so the world hears them. But we belong to GOD, and people who know GOD listen to us, while people who do not belong to GOD do not listen to us. This is how you can tell the difference between the spirit of truth and a false spirit.
