13 Greater love has no one than this, that someone lay down his life for his friends
John 15:13 (ESV)
16 By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers.
I John 3:16 (ESV)
God Is Love
7 Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God. 8 Anyone who does not love does not know God, because God is love. 9 In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. 10 In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. 11 Beloved, if God so loved us, we also ought to love one another.
I John 4:7-11 (ESV)
