Joseph Smith
"I hope I shall see [my friends] again, that I may toil for them, and administer to their comfort also. They shall not want a friend while I live; my heart shall love those, and my hands shall toil for those, who love and toil for me, and shall ever be found faithful to my friends. Shall I be ungrateful? Verily no! God forbid!" (Teachings of Presidents of the Church: Joseph Smith, p. 462).
