4:7 Beloved, let us love one another: for love is of God; and every one that loveth is begotten of God, and knoweth God. 4:8 He that loveth not knoweth not God; for God is love. 4:9 Herein was the love of God manifested in us, that God hath sent his only begotten Son into the world that we might live through him. 4:10 Herein is love, not that we loved God, but that he loved us, and sent his Son `to be' the propitiation for our sins.
