They went out from us, but they were not of us: for, if they had been of us, they would have remained with us; but they went out, that they might be made manifest that they were not all of us.

Beloved, believe not every spirit; but prove the spirits, whether they are from God: for many false prophets have gone out into the world.

They are of the world: there fore, they speak of the world, and the world hears them.
