In the encyclical about hope running into about 75 pages, Pope Benedict is not proposing a facile hope in heaven undoing injustices of life on earth. Indeed, this is where he brings in Dostoyevsky. The Pope asserts that "the last Judgment is not primarily an image of terror, but an image of hope". A world without God is a world without hope, and "God is justice". Only God can provide the justice that sustains hope in the better future—the eternal life—for one and all. "God is justice and creates justice. This is our consolation and our hope. And in his justice there is also grace. This we know by turning our gaze to the crucified and risen Christ. Both these things—justice and grace—must be seen in their correct inner relationship."
With justice comes grace, yet "grace does not cancel out justice. It does not make wrong into right. It is not a sponge which wipes everything away, so that whatever someone has done on Earth ends up being of equal value. Dostoyevsky, for example, was right to protest against this kind of Heaven and this kind of grace in his novel "The Brothers Karamazov". Evildoers, in the end, do not sit at table at the eternal banquet beside their victims without distinction, as though nothing had happened."
