After revealing a more clear meaning of "Eternal Punishment" and "Eternal Damnation", the revelation in D&C 19 goes on to say:

"Therefore I command you to repent—repent, lest I smite you by the rod of my mouth, and by my wrath, and by my anger, and your sufferings be sore—how sore you know not, how exquisite you know not, yea, how hard to bear you know not. For behold, I, God, have suffered these things for all, that they might not suffer if they would repent; But if they would not repent they must suffer even as I; Which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit—and would that I might not drink the bitter cup, and shrink—Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men." (D&C 19)

They way I have interpreted this in my mind is that we have to suffer the sins of everyone and feel all the same pain Christ felt. However I have always had a problem with the injustice of suffering for everyone's sins, simply because we didn't reconcile our own.

Today, I had another thought. Let's say in one life we are a parent that abuses our children, beats them, burns them, hates them. Then when we pass this realm, we see what we've done, and we are submerged into a lake of fire and brimstone of regret, we determine that we never want to abuse the innocence of life in such a way ever again, and so we work with God to formulate a plan for our next probation, to we determine that the best course of action. We know we have deeply offended, and we realize that there will be others who will return, like us, and abuse their children. We see ourselves in them, we want them to be forgiven also, and we are willing to bear the burden of being beaten, burned and hated (also knowing some child or children that come to their family will have to endure that), and eventually forgiving them and finding our way back to peace and love. We tremble at the thought, but our willingness to bear the burden cleanses us. Then we suffer as he suffered, not in all things yet, but we bear the abuses we afflict, and find our way back to the Father.
