Elder Robert D. Hales of the Quorum of the Twelve Apostles referred to personal experience in emphasizing the importance of being a light for others:
“Growing up on Long Island, in New York, I understood how vital light was to those traveling in the darkness on the open sea. How dangerous is a fallen lighthouse! How devastating is a lighthouse whose light has failed!
“We who have the gift of the Holy Ghost must be true to its promptings so we can be a light to others.
“‘Let your light so shine before men,’ said the Lord, ‘that they may see your good works, and glorify your Father which is in heaven’ [Matthew 5:15–16].
“We never know who may be depending on us. And, as the Savior said, we ‘know not but what they will return and repent, and come unto me with full purpose of heart, and I shall heal them; and ye shall be the means of bringing salvation unto them’ [3 Nephi 18:32]” (in Conference Report, Apr. 2002, 82; or Ensign, May 2002, 71).
