President Uchdorf defines hope a number of different times in his recent conference talk: The Infinite Power of Hope.
Hope is one leg of a three-legged stool, together with faith and charity. These three stabilize our lives regardless of the rough or uneven surfaces we might encounter at the time.
Hope has the power to fill our lives with happiness.2 Its absence—when this desire of our heart is delayed—can make “the heart sick.”
Hope is a gift of the Spirit.
It is a hope that through the Atonement of Jesus Christ and the power of His Resurrection, we shall be raised unto life eternal and this because of our faith in the Savior.5 This kind of hope is both a principle of promise as well as a commandment,6 and, as with all commandments, we have the responsibility to make it an active part of our lives and overcome the temptation to lose hope.
Hope in our Heavenly Father’s merciful plan of happiness leads to peace,7 mercy,8 rejoicing,9 and gladness.
The hope of salvation is like a protective helmet;11 it is the foundation of our faith12 and an anchor to our souls.
