By this you know the Spirit of God: every spirit who confesses that Jesus Christ has come in the flesh is of God, and every spirit who doesn’t confess that Jesus Christ has come in the flesh is not of God; and this is the spirit of the Antichrist, of whom you have heard that it comes. Now it is in the world already.
Every Scripture is God-breathed and profitable for teaching, for reproof, for correction, and for instruction in righteousness, that each person who belongs to God may be complete, thoroughly equipped for every good work.
