56:10 John, realizing that brotherly love was waning in the church, urged upon believers the constant need of this love. His letters to the church are full of this thought. "Beloved, let us love one another," he writes; "for love is of God; and everyone that loveth is born of God, and knoweth God. He that loveth not knoweth not God; for God is love. 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. Herein is love, not that we loved God, but that He loved us, and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we ought also to love one another."
