Gordon B. Hinckley said this quote

How sweet is the assurance, how comforting is the peace that come from the knowledge that if we marry right and live right, our relationship will continue, notwithstanding the certainty of death and the passage of time. Men may write love songs and sing them. They may yearn and hope and dream. But all of this will be only a romantic longing unless there is an exercise of authority that transcends the powers of time and death.
