Dear friends, do not believe every spirit, but test the spirits to determine if they are from God, because many false prophets have gone out into the world.
1 John 4:1 HCSB
Some of those who profess to speak the word of God are not from God, but are from the devil; they have been sent to twist the word of the LORD for the devils gain, which is your life. If someone professes doctrine that you are unsure of, test it against the Scriptures as the Scriptures do not lie. The word of God is eternal and true, test all against it.
