Weaknesses

"This is a world in which we are to prove ourselves. The lifetime of man is a day of trial, wherein we may prove to God, in our darkness, in our weakness, and where the enemy reigns, that we are our Father's friends, and that we receive light from him and are worthy to be leaders of our children-to become lords of lords, and kings of kings-to have perfect dominion over that portion of our families that will be crowned in the celestial kingdom with glory, immortality, and eternal lives." 
--Brigham Young, "Teachings of Presidents of the Church", Brigham Young 13 Preparing for Eternal Progression, 85
