1 John 4:1-3, 7, 15

Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: and every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.

Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.

Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.
