A common principle I have heard taught in the LDS church is that Jesus suffered for our sins. Actually, that he suffered for all our pains. One of the most common scriptures to support this principle is 2 Ne 9:21
He suffereth the pains of all men, yea, the pains of every living creature, both men, women, and children, who belong to the family of Adam.
Seems reasonable enough. But why did he do it?
Sure, he suffered for our sins, so we could be forgiven of them and then live with God again. But what about all the other pains? Why suffer for our sadness? Our grief? Our hunger? Our heartbreaks? Our sicknesses? What possible redemptive value can there be in those sufferings?
Verse 22 seems to provide an answer.
He suffereth this that the resurrection might pass upon all men, that all might stand before him at the great and judgment day.
In order for Jesus to be resurrected â€” and in turn for us to be resurrected â€” he needed to overcome death. But for Jesus, it wasn’t just simply separating his spirit from his body. It wasn’t just willing his heart to stop. For Jesus to die, he had to overcome mortality.
Jesus suffered all our mortal pains so he could experience â€” and then overcome â€” mortality.
