Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.
Dear friends, do not believe everyone who claims to speak by the Spirit. You must test them to see if the spirit they have comes from God. For there are many false prophets in the world.
For what human being knows what is truly human except the human spirit that is within? So also no one comprehends what is truly God's except the Spirit of God.
