irreversible

Let us for a moment consider what the Christian is necessarily guilty of "hoping for" if we reverse the arrow of time.

By this I mean, if "God" decided to reverse the clock of time itself - which a "God" who can do anything can do as easily as He can create a universe from nothing at all - so that in two thousand years Christians would eventually find themselves living in the days of Jesus, those Christians would suddenly be faced with a dilemma that demonstrates just how utterly useless, and therefore how utterly false, their modern version of Christianity really is, especially when it comes to defining morality.

This is because, if time suddenly did move in reverse, and the past became the future, the Christian would suddenly be faced with the question of whether people have free-will, and what they should therefore do with it, if in fact they do. And this question would then be followed by an even worse question: what to do about Jesus himself?

For if people had free-will, and were likewise aware that Jesus was the "son of God," as Christians claim, they would have to decide if they should torture and murder Jesus all over again, in order to save their own souls from eternal damnation, or spare him instead, and risk their own everlasting souls to do so in the process. 

In this situation, the Christian today would still "hope" for their salvation, as it were, but they would also be forced to accept that the only way they can obtain that salvation is to further "hope" that, two thousand years from now, the Christians who encounter Jesus himself will nevertheless torture and murder their "lord and savior" anyway, even though they will be just as aware as Christians are today that Jesus Christ is the undeniable "son of God."
