The Prophet Joseph Smith explained: “More painful to me are the thoughts of annihilation than death. If I have no expectation of seeing my father, mother, brothers, sisters and friends again, my heart would burst in a moment, and I should go down to my grave.
“The expectation of seeing my friends in the morning of the resurrection cheers my soul and makes me bear up against the evils of life. It is like their taking a long journey, and on their return we meet them with increased joy” ( Joseph Smith [manual], 176). The Lord further clarified that we should mourn only for those who do not have a hope of a glorious resurrection (see D&C 42:45–47).
