Several of the sisters I met with in the temple had difficult trials during the past year. One had both her knees replaced, yet she could kneel. Another had by-pass surgery, yet she talked of working in her yard. A third was in a head-on collision when an oncoming driver fell asleep at the wheel and came across the median. She is fine, but her pinky on her right hand doesn't work as well as it could.
All of these sisters bless the lives of others, even through their own trials.
Therefore, he giveth this promise unto you, with an immutable covenant that they shall be fulfilled; and all things wherewith you have been afflicted shall work together for your good, and to my name's glory, saith the Lord.
(Doctrine and Covenants | Section 98:3)
