God sometimes lightens, and sometimes removes burdens

Burdens are a part of mortality. Sometimes, after much faith, God removes them. Sometimes, He just lightens the load. As mortals, this can be confusing. We find ourselves crying "But God, I don't want it to hurt less, I want it to stop hurting me at all! Why?" As mortals, it is hard to see the reasons, sometimes we never understand why we had to go through something, or watch a loved one suffer. Often we find ourselves wondering when it will be over. We need to have patience and accept The Lord's time. We need to be as the people of Alma:
"And now it came to pass that the burdens which were laid upon Alma and his brethren were made light; yea, the Lord did strengthen them that they could bear up their burdens with ease, and they did submit cheerfully and with patience to all the will of the Lord." (Mosiah 24:15)
If we have faith, God will sometimes remove burdens, but not before it fits in His timetable. As hard as this is, we need to accept this. Sometimes all we can do is ask Him for comfort that there will be a eventual relief. President Eyring talks about this in depth in his October 2012 talk, "Where is the Pavilion"
If you are not familiar with that talk, I encourage you to read it.
I testify that God can remove any burden, whether it be sin, pain, sorrow, infirmity, bondage, or whatever you are yoked with. I hope for this in my life, as I have great need for this. I say these things in the name of Jesus Christ, amen.
