By this we know love, because He laid down His life for
us. And we also ought to lay down our lives for the brethren.
But whoever has this world's goods, and sees his brother in need, and shuts up his heart from him, how does the love of God abide in him?
My little children, let us not love in word or in tongue, but in deed and in truth.
1 John 3:16-19
