'Every' in the Bible

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.

This is how you know the Spirit of God: Every spirit who confesses that Jesus Christ has come in the flesh is from God.

But every spirit who does not confess Jesus is not from God. This is the spirit of the antichrist; you have heard that he is coming, and he is already in the world now.
