Christians: how do you reconcile yourself to the view that all unsaved people end up in hell to suffer eternal torment?
Your list
almost included Christians like myself. There are those of us who believe that hell is a future event, not an existing place. And that it will be finite, not eternal. Despite whatever intense debate such a position tends to incite (which is often quite rewarding), there certainly are people who hold this position, who believe the scriptures that describe immortality as a something given only to the redeemed "at the last trumpet." In that day, the perishable is clothed with the imperishable, the mortal with immortality—ergo, the unsaved remain perishable and mortal; i.e., their fiery end is finite. As Criada astutely noted (Msg. #30), "most of the eternal torture stories owe more to medieval art and literature than to the Bible."
What will be my reaction to the countless billions destroyed in the fires of hell? Probably a sober reflection on the sovereign justice of God. What about crying and feeling profound sadness? I experience that sort of reaction now in this life, here in the thick of the spiritual struggles where I remain ignorant about the truth of their lives. At the final end of all things, my emotional turmoil will be consummated at the throne of God, where the lives and choices of the damned will be contextualized in the sovereign judgment of the Creator, their true colours being exposed. Then I will reflect with an informed understanding the justice of God, the object of my inexpressible love. I will neither cry nor celebrate in the face of such a sober reality.
It seems to me that the only rational and moral response would be . . .
. . . a conclusion that follows only under your chosen moral theory, which we know nothing about and consequently have no reason to think is coherent or valid. Without knowing anything at all about your chosen moral theory, the Christian response is left to answer the issue under the Christian moral theory, which probably differs quite dramatically from yours.
If one truly believes in hell, and truly loves others, how can one not be constantly tormented by the thought that most of humanity, and probably some of ones own acquaintances, are heading for [the fires of hell] . . . For a true Christian, who both believes in hell and has any shred of empathy, how can anything else in life remotely approach the significance of this dreadful fact?
1. Because the love we have for mankind is not greater than the love we have for God. For the Christian, God comes before all things. Over the love I have for this and that person exists the far greater love I have for God.
2. Because the whole truth and every secret thing will be exposed in the light of God's throne of judgment and we'll truly understand, whereas before (life right now) we did not know the whole true story. Every choice, every deed, every feeling and every thought, no matter how carefully the unsaved had kept it guarded during their life, at the throne of God it will all be revealed and his judgment will be understood.
3. It seems that you subscribe to the values and morals of Secular Humanism (whether explicitly or coincidentally). And that's fine. However, Christians do not. Our commitment is to God, not mankind. The love and empathy that Christians have for mankind is communicated through and empowered by the love and commitment we have to God in Christ Jesus; our love for the created flows from our love for their Creator, who created all mankind in his image.
P.S. It is interesting to note that under the "Denies Hell" heading, you have listed options that involve hell existing. If they believe, for example, that "hell is only for really, really bad people like Adolf Hitler," well then they are not exactly denying hell, are they?
