1 John 4:8-10 The person who doesn’t love doesn’t know God, because God is love. God has shown us his love by sending his only Son into the world so that we could have life through him. This is love: not that we have loved God, but that he loved us and sent his Son to be the payment for our sins.
The Message)7-10 My beloved friends, let us continue to love each other since love comes from God. Everyone who loves is born of God and experiences a relationship with God. The person who refuses to love doesn’t know the first thing about God, because God is love—so you can’t know him if you don’t love. This is how God showed his love for us: God sent his only Son into the world so we might live through him. This is the kind of love we are talking about—not that we once upon a time loved God, but that he loved us and sent his Son as a sacrifice to clear away our sins and the damage they’ve done to our relationship with God.
NKJV) 8 He who does not love does not know God, for God is love. 9 In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. 10 In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.
No matter which version of the Bible you may read the message of these verses is clear. God is love and without God there is no knowledge of God. Know God and you know love, No God and there is no love.
