Elder Robert D. Hales of the Quorum of the Twelve Apostles explained that one reason the Lord does not always shield His servants from persecution is that trials allow us to experience refining, strengthening blessings:

            “There is meaning and purpose in our earthly challenges. Consider the Prophet Joseph Smith: throughout his life he faced daunting opposition—illness, accident, poverty, misunderstanding, false accusation, and even persecution. One might be tempted to ask, ‘Why didn’t the Lord protect His prophet from such obstacles, provide him with unlimited resources, and stop up the mouths of his accusers?’ The answer is, Each of us must go through certain experiences to become more like our Savior. In the school of mortality, the tutor is often pain and tribulation, but the lessons are meant to refine and bless us and strengthen us, not to destroy us” (“Faith through Tribulation Brings Peace and Joy,” Ensign or Liahona, May 2003, 17).
