Joseph Smith

“That friendship which intelligent beings would accept as sincere must arise from love, and that love grow out of virtue, which is as much a part of religion as light is a part of Jehovah. Hence the saying of Jesus, ‘Greater love hath no man than this, that a man lay down his life for his friends.’ [John 15:13.]” (Teachings of Presidents of the Church: Joseph Smith, p. 463).
