Dad was a constant example for me on my mission. After he had his stroke and lost the use of his left hand (he's left handed) he wrote me the following letter:
"Dear Sisters Sparks, Elder Sparks (Note: Alicia, Michelle and me, Taylor, were all currently serving a mission)
You've seen my blazing 2 finger typing skills, now it's reduced by 50%. I have to pick up 1 more finger on my right hand then look out Mama. Things are fine at home now. I'm out of the hospital. You fart one time in public and they run you out of the place. I'm very optimistic about gaining back the use of my left hand. Most of the left leg has come back already. I have looked for a reason for this happening right now. I think I have found one. I have learned again how much your Mom loves me. She came up to the hospital every day and climbed on the bed cuddled with me. It made me realize how much she cared for me. This is all for today since it has taken me an hour type.
Life is great. "
As far as being faithful to God even in the face of extreme trials Dad would even give Job a run for his money.
