Faith and love are demonstrated by giving of oneself for others

Scripture reference

1 John 3:16–18 (ASV)

16Hereby know we love, because he laid down his life for us: and we ought to lay down our lives for the brethren. 17But whoso hath the world’s goods, and beholdeth his brother in need, and shutteth up his compassion from him, how doth the love of God abide in him? 18My little children, let us not love in word, neither with the tongue; but in deed and truth.
