1 John 4:7

⁵ They are of the world: therefore speak they of the world, and the world heareth them.

⁶ We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.

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

⁸ He that loveth not knoweth not God; for God is love.

⁹ In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him.
