The sweetness that we can taste comes from the gospel of Jesus Christ and from the tender assurances of the Holy Ghost. Death is not (or will not be) a stranger to any of us; sooner or later we all see death visiting those we know and love. Sometimes he appears as a merciful end to suffering and other times he appears heartless and cold, robbing us of those we love too soon in life. One day he will call at each of our doors, beckoning us to him. Death is not the enemy, he simply brings the key that opens the door leading from this life into the next. Sometimes he comes riding in a chariot of fire pulled by flaming horses (see 2 Kings 2:11); other times he silently appears without fanfare. Death is not the end; it is a door - a small step in our lives but a giant leap towards our eternal progression. Christ suffered and died that we might all live again and enter again in to the presence of the Lord.
"For behold, [Christ] surely must die that salvation may come; yea, it behooveth him and becometh expedient that he dieth, to bring to pass the resurrection of the dead, that thereby men may be brought into the presence of the Lord. Yea, behold, this death bringeth to pass the resurrection, and redeemeth all mankind from the first death—that spiritual death; for all mankind, by the fall of Adam being cut off from the presence of the Lord, are considered as dead, both as to things temporal and to things spiritual. But behold, the resurrection of Christ redeemeth mankind, yea, even all mankind, and bringeth them back into the presence of the Lord." (Helaman 14:15-17).
