President Brigham Young taught,

“All intelligent beings who are crowned with crowns of glory, immortality, and eternal lives must pass through every ordeal appointed for intelligent beings to pass through, to gain their glory and exaltation. Every calamity that can come upon mortal beings will be suffered – to prepare them to enjoy the presence of the Lord. … Every trial and experience you have passed through is necessary for your salvation.”
