16 By this perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
17 But whoever has this world's goods, and sees his brother have need, and shuts up his heart of compassion from him, how dwells the love of God in him?
18 My little children, let us not love in word, neither in tongue; but in deed and in truth.
