Elder Joseph B. Wirthlin (1917–2008) of the Quorum of the Twelve Apostles identified the source of living water: “The Lord provides the living water that can quench the burning thirst of those whose lives are parched by a drought of truth. He expects us to supply to them the fulness of the gospel by giving them the scriptures and the words of the prophets and to bear personal testimony as to the truth of the restored gospel to alleviate their thirst. When they drink from the cup of gospel knowledge, their thirst is satisfied as they come to understand our Heavenly Father’s great plan of happiness” (in Conference Report, Apr. 1995, 23; or Ensign, May 1995, 19).
