I have a dear friend whose central attribute of character is compassion. She questions why some people have to suffer so much in this life while others don't? It positively wrecks her soul when she hears of someone's pain. I have thought about her question long and hard and I offer here my understanding which admittedly comes from a finite and limited mortal view.
I believe fully and completely in the principle of free agency. Because of it we can never blame God for anything we experience. I believe we exercised the privilege of this agency even before we were born as spirits, while we were so called 'intelligences' (Abraham 3:22). It makes sense to me that back then we chose to be born as spirits with a view to be embodied in flesh on our journey to godhood. I believe that in the spirit world we advanced on different levels and that each of us mapped out a plan for our mortal experience which would enable us to work out our salvation. In other words, we each chose our life's difficulties. We wanted to advance ourselves and because of that there were certain qualities, characteristics and attributes we wanted to acquire and develop. Our lives were planned with challenges that corresponded with the goals we had to give us the desired end. We also opted for difficult situations for the benefit of others who we wanted to help. I do not believe that we are here to be subjected to random and arbitrary experiences . To randomly have to suffer without any cause would be supreme injustice. Since God is just this theory of random suffering does not ring true to me. Hence my belief is that we chose our suffering. That's justice and justice can only exist where there is free agency. The idea that we chose afflictions such as abuse, neglect, physical pain, mental anguish, starvation, poverty and horrific earthly experiences is a bitter pill to swallow now that we are here and are experiencing it. Our understanding is finite and our eternal perspective difficult to maintain.
Two questions arise out of this theory of free choice. Firstly, did we really understand what suffering was having never experienced it prior to mortality? Many of us would argue that we did not. For instance, a woman does not know what child bearing is like until she is wheeled into the labour ward. The interesting point is that she chooses it again even after experiencing it once. I would argue that we understood exactly and perfectly what suffering would be like and that this understanding was given to us by the power of God's spirit, He himself having experienced mortality and having experiential knowledge thereof. This truth is confirmed to me by the fact that a third of God's children backed out of the Plan because they understood exactly what mortality was going to be like and therefore opted for Satan's plan with the promise of 'free lunch' (D&C 29:36). The understanding must have been incredibly comprehensive and thus Satan's plan very appealing for those spirits to forsake the all consuming love of God the Father and his promise of eternal life with Him.
Secondly, if we understood it so well how could we possibly choose to suffer so cruely? Those who kept their second estate and were brave enough to embrace mortality with the full understanding of what that actually meant must have been brave enough to embrace it for only one reason: they had explicit faith in Jesus Christ and His power to save us from it. So dependable and honourable was Christ from the beginning that we knew with certainty that He would see the task to the end and save each and every one of us. I believe even those who were not to know Him in this life chose His plan because they knew that in the end the Atonement would bring them healing.
I see other reasons for suffering in mortality besides our desire for self-advancement such as a test of faith but all of these reasons pale in significance to the greatest reason of all. Jesus plainly demonstrated this principle when He healed people of their physical infirmities during this ministry. He didn't heal people just out of His compassion. There was an important lesson to be learnt from it. It is most obvious in the story of a woman who suffered from 'an issue of blood' for 12 years. The Gospel of Mark records that she suffered many things at the hands of many physicians and none could heal her while she grew worse. Imagine hemorrhaging for twelve years with no end in sight. Out of desperation was born faith that Jesus could heal her and heal her He did merely by the touch of His garment. Both Matthew and Mark cite Christ saying to her that her faith had made her whole but Luke adds something more that the Saviour said to her: "Go in peace" (Luke 9:48) denoting spiritual healing as well as the physical one. What was He trying to teach the people He healed? That the greatest suffering is not of the body but of the spirit and it is this suffering that we stand to be subjected to if we do not come unto Him. The Saviour expressly said if we do not repent of our sins and allow His Atonement to pay the price of sin we will have to suffer even as He (D&C 19:15-18). The suffering of this life would pale in significance compared to such suffering.
The greatest lesson of suffering is that it is meant to bring us to Christ, the fountain of our salvation. I hear people say, "God won't give you anything that you can't handle" but I believe quite the opposite is true. He will give us whatever it takes to bring us to Him for our eternal welfare is His primary concern. Whether we learn that suffering is meant to bring us to Him here and now or are taught this principle after this life, it matters not. By experiencing suffering here we learn what it actually is and most importantly, that we don't want it and that lesson is of eternal advantage. We live in a fallen world where Satan reigns supreme. We will experience suffering from physical bodies, mental illness, from sin and from actions of others. It all comes for a purpose even if we don't understand what it is. What we need to know and have faith in is that the Saviour has atoned for it ALL. In Him there is freedom, in Him there is peace, in Him there is joy. May we strive to live so that one day we may find refuge and rest in the shadow of His protective arms where rests eternal life.
