By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, which you have heard is coming, and now it is already in the world.
For who among people knows the thoughts of a person except the spirit of the person that is in him? So also the thoughts of God no one knows, except the Spirit of God.
