1 John 3:16-20

16By this we know love, because He laid down His life for us. And we also ought to lay down our lives for the brethren.

17But 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?

18My little children, let us not love in word or in tongue, but in deed and in truth.

19And by this we know that we are of the truth, and shall assure our hearts before Him.

20For if our heart condemns us, God is greater than our heart, and knows all things.
