Do all Jews, Hindus, Muslims, followers of all eastern religions, tribesman in Africa, Central and South America, Eskimos, South Pacific Islanders...not to mention the millions and millions of people who died before Jesus was born, do they ALL go to hell because they haven't or even had the opportunity to accept Jesus Christ as their personal savior?
is "yes", they are doomed to eternal torture. Correct?
As to the people who lived before Christ, they were justified by faith, just like we are. Christ was revealed in types, symbols, promises, and tons of other stuff in the Old Testament. Jews and the surrounding nations put their hope in the promised one who would come and fix the cosmic war as the "seed of the woman" who would "smash the serpent's head" although his own heel would be crushed. This promise, given immediately after the fall, is expanded, explained, pictured, and looked to thorought the period before Christ. They had faith, we have faith. Theirs was in the coming Savior, ours is in the Savior who has come. No difference in substance, just the amount of info we have.
You have a bad picture of hell. Men only get what they eternally ask for. The idea that men in hell would repent and come to Christ if they "only had the chance" is hocum. There is an eternal "Thy will be done" or "MY will be done" and God both honors and effectuates that meaningful choice by His creatures. If you could go into the bowels of hell to see the most pathetic damned soul, in the agonies of his own dissolution as an eternal being, you would find an eternal venom, spite, hate and rebellion against God, so that if the price to heaven is submission, humility, and reception of grace, the answer would be "not 'no' but HELL NO!" God simply gives men what they eternally wish for, which is banishment from his presence. This is hell.
