The individual testimonies of Latter-day Saints members comprise the great strength of the church.
      Such conviction "is the wellspring of faith and activity. It is difficult to explain. It is difficult to quantify. It is an elusive and mysterious thing, and yet it is as real and powerful as any force on the earth."
Testimony is something that cannot be refuted. Opponents can be clever and persuasive. But when a member testifies, "I know," there can be no argument.
"We grow in faith and knowledge as we serve, as we study, as we pray."
      It is personal testimony that turns people's lives around.
      "This is the element which motivates the membership to forsake all in the service of the Lord. This is the quiet, encouraging voice which sustains without pause those who walk in faith down to the last days of their lives."
      Testimony is a gift from God to man and overrides wealth or poverty when one is called to serve.
      "It is what is moving the work of the Lord forward across the world. It impels to action. It demands that we do what we are asked to do."
