Hope For All

If death is the finish line for choosing between heaven and hell, why did Father withhold this information for millenia?  Why do we not read of this in Genesis where sin began?  Why did Father not clearly explain this?  How can we account for this seemingly callous disregard of all those millions and perhaps billions who lived and died before Jesus' Advent?  Could anything be more important?  If Father has no other options, would He not give all an opportunity to hear of the coming of Christ and His atoning sacrifice?  Would not such dire consequences warrant such a chance?
Or is it possible that death is not the finish line?  That those who sleep in death await their opportunity?  That Father has something more glorious in store?  That He has given the keys to death and the unseen (hell) to Jesus who will use them in due time? That each, at his appointed time, will meet his Savior face to face, have his blindness removed, and at that moment will bow the knee and confess with his tongue to the Glory of the Father?
Why are we so dead set on sending the vast majority of mankind to eternal punishment?  Are we so arrogant as to believe that we would have fared any better than they given the same circumstances?  Does any honestly believe that they chose Jesus due to some superior intellect or good sense of their own?  Can we not believe the scripture that tells us that we are all the same without exception?

"What, then? are we better? not at all! for we did before charge both Jews and Greeks with being all under sin, according as it hath been written--`There is none righteous, not even one; There is none who is understanding, there is none who is seeking after God. All did go out of the way, together they became unprofitable, there is none doing good, there is not even one." [Rom 3:9-12]

Is it so hard to believe that He chose us and not the other way around?  Is that not the most hopeful of the two alternatives?  For if it is Father who does the choosing (and the scripture declares it so) then all indeed have Hope!
