"You get what you get, and you don't throw a fit!"
We all get something. We get life, and we get mortal experiences that are designed to help us reach our highest potential as children of a loving God. As was mentioned in our recent General Conference by Elder D. Todd Christofferson:
"Life will be long enough for each spirit, and each body will qualify for resurrection."
Mortal experiences are sometimes quite awesome (chocolate, roses, the smell of my husband's neck, and hugs from my kids -- to name a few). And some are quite difficult, because mortality is messy. The good news is that the difficult parts are intended to be temporary (like my daughter's first wiggly baby tooth). But the gains that we make during these experiences are intended to last forever. God has consecrated every affliction to my gain, and these gains are everlasting treasures that far outweigh their price. I wouldn't dare throw a fit!
Instead, I feel both obligated and privileged to look for ways to consecrate these gains back to God for a good purpose.
