John's words that God will "wipe away every tear" can be understood to mean that now, when the world has been completely transformed and there is no place for evil in it, the faithful have nothing left to cry about: now, in the fullness of the Kingdom, they are no longer threatened by any loss or any separation from those who are close and dear to them. Yet this is probably not the whole truth. After all, any utopia, even the most radiant and shining one, any project of the most wonderful and most just society, has never answered the question of what is to become of those who did not live, and will not live, to see the triumph of that very utopia.
In practice, fighters for a "bright future" quite often proved to be selfless enthusiasts, often ready to give not only all their strength but even their lives to accomplish something they themselves would never have any chance of seeing during their lifetime. But such enthusiasm itself testifies that the people who had it drew strength and inspiration not from that "bright future," which did not yet exist, but from some other source.
When it comes to the Kingdom, the problem, at first glance, is solved by the universal resurrection: through it everyone receives the opportunity to share in the Kingdom to which he was faithful in life. And yet: tears that have been shed cannot be taken back; what happened, happened, and past evil remains real to the same extent that our past is real to us at all. What, then, can be done about this? The answer here, strangely enough at first glance, may be the forgiveness and liberation of a repentant sinner from every sin, including sin committed consciously, which is given to everyone in the Kingdom.
Earlier, before Christ came into the world, it was possible to repent of any sin, but to be cleansed from it, to be freed from the consequences of what had been done, was possible only if the sin was not voluntary, if the will of the one who sinned had not spiritually fed the sinful act. In any other case the consequences of the sin weighed on the person who committed it throughout his life, and even after death the evil he had done did not disappear, sometimes affecting the people connected with the sinner, or the descendants both of the one who sinned and of the people connected with him.
This situation could be changed only by recreating the world anew. Or by bringing into it the Kingdom, which by its breath is able to transform it. But such transformation, which fully frees from the power of any sin, also means that Christ has the power to change not only the future, but the past as well. This is not surprising: in the Kingdom, it appears, past, present, and future relate to one another in a way that is not as linear as in the untransformed world.
But if that is so, then on the day of the Kingdom's triumph evil will remain neither in its eternal present nor in that past where evil still had a place before the Kingdom was revealed in all its fullness. It will not remain because the past itself will not remain: there will remain only that underside of the new world, where the evil that once possessed the world is driven out, that outer darkness of which the Savior speaks, which in John's vision is revealed as the "pit filled with fire," and the eternal present of the Kingdom, where there will be no place for any evil, whatever time it belonged to by the measures of the former world.
