“This is my commandment, that you love one another as I have loved you. Greater love has no one than this, that someone lay down his life for his friends" John 15:12-13 (ESV).
"By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers. But if anyone has the world’s goods and sees his brother in need, yet closes his heart against him, how does God’s love abide in him? Little children, let us not love in word or talk but in deed and in truth" 1 John 3:16-18 (ESV).
