We are the light of the world. We have received the inspiration of Almighty God. We have received a testimony of the gospel, and we do know that God lives, that Jesus is the Christ, that Joseph Smith was a prophet of God. . . . Every true Latter-day Saint has this testimony burning within his or her heart. Now, are we so living that the good deeds that we perform bring credit to the work of God? Are our examples worthy of the imitation of all men? Do we by our example show that we have faith in the gospel?” (Teachings of Presidents of the Church: Heber J. Grant, p. 97).
