There is absolute “Truth”. Jesus Christ is the absolute Truth and the only way to peace with God. “Salvation can be found in no one else. Throughout the whole world, no other name has been given among humans through which we must be saved.” (Acts 4:12)
1 John 4
Common English Bible (CEB)
Dear friends, don’t believe every spirit. Test the spirits to see if they are from God because many false prophets have gone into the world. This is how you know if a spirit comes from God: every spirit that confesses that Jesus Christ has come as a human is from God, and every spirit that doesn’t confess Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and is now already in the world. You are from God, little children, and you have defeated these people because the one who is in you is greater than the one who is in the world. They are from the world. So they speak from the world’s point of view and the world listens to them. We are from God. The person who knows God listens to us. Whoever is not from God doesn’t listen to us. This is how we recognize the Spirit of truth and the spirit of error.
