That. of course, begs the question of what I, or any other mere mortal, could have done that so seriously offends God? One can understand it in the case of mass murderers, child abusers and so forth. But something like my occasional grumpiness or inability to suffer fools gladly, or even my direct and occasionally pugnacious approach to helping those who have been treated badly and unfairly, is surely not cause for God's wrath? Or is God really so thin-skinned? In other words, what did I, or the majority of largely inoffensive humans, collectively or indidvidually, do that requires so much forgiveness?
In the matter of who is in charge of our eternity, given that we have free will, then it can only be ourselves. The Stoics teach that we can be in pain or ecstasy due to external causes, but to suffer or enjoy is our choice. In other words, it is within our power, and only our power, to remain calm, balanced and content either in Heaven or in Hell.
If I am physically resurrected and tossed into Hell to be tormented, then the pain is only in the body. That physical pain can be overcome, overridden or ignored by use of the correct mental attitude is a matter of daily proof for many people. If there is no physical resurrection then there is no way for God or Satan to make me suffer unless I choose to. Strip my will, and you strip my individuality, leaving nothing but the reptile brain to be punished, and the reptile brain is incapable of either good or evil.
Put me in Heaven, and I will likely disregard its pleasures in order to plead the case for those people in Hell who ought not, in justice, to be there. As well as demanding that anyone in Heaven who should be in Hell be sent there!
