We are all infants compared to the beings of glory and grandeur we are designed to become. No mortal being advances from crawling to walking to running without frequent stumbles, bumps, and bruises. That is how we learn.
If we earnestly keep practicing, always striving to keep God’s commandments, and committing our efforts to repenting, enduring, and applying what we learn, line upon line, we will gather light into our souls.
Elder Dieter F. Uchtdorf, "God Among Us", General Conference, April 2021
We all go through days that are difficult. Days that are stressful and frustrating. Days we just want to leave behind in the rear view mirror.
When our burden feels the heaviest, wouldn't we want someone to help lift that load? I know I would. Especially as my strength slackens and the load starts crushing me under its immense weight.
One word stuck out to me in this quote... "enduring". And enduring can be very hard to do. Because you just want to rest. You just want to relax and put that heavy load down for a bit.

Well, we can't put it down, but there is Someone who can help carry that load, and carry the majority of it, even all of it, I might add. All we have to do is let Him do so. That's it.
"Come unto me, all ye that labour and are heavy laden, and I will give you rest." - Matt 11:28
Rest! That is what we all want.
