Spirits who, in their lifetime, led a conscientious life but did not believe in any religion will also return to earth at the granted time to receive the benefit of returning resurrection. They will guide conscientious earthly people to seek out Christ at the Second Advent, attend him, and assist him in fulfilling God’s Will.
The ultimate purpose of God’s providence of restoration is to save all of humanity. Therefore, God intends to abolish hell completely after the passage of time necessary for each individual to make restitution for his sin. If hell were to remain eternally in the world where God’s purpose of goodness is fulfilled, it would contradict the perfection of God, His ideal, and His providence of restoration.
Even fallen parents cannot feel joyful when one of their children is unhappy. Is this not even more true for God, our Heavenly Parent? It is written, “The Lord... is forbearing toward you, not wishing that any should perish, but that all should reach repentance” (II Pet. 3:9). Accordingly, hell cannot remain forever. No trace of hell will remain in the ideal world, which is the fulfillment of God’s deepest desire.
In the Last Days, when the time is ripe, evil spirits will descend to evil people on earth of the same spiritual level and assist them to accomplish God’s Will. Indeed, even the demons testified that Jesus was the Son of God (Matt. 8:29). By participating in these various dispensations over a long course of time, all people will gradually converge toward the goal of God’s ideal world.
