Jesus fulfilled a great many prophecies, healing sick and demon-possessed individuals and even resurrecting the dead. But he promised even greater things to come after him, and he said that he would return in the last days as a spirit person ruling from heaven. Satan was to be cast out of heaven and thus confined to the earth in the last days, bringing trouble to earth's seething masses, while a cleansed heavens allowed the beginning of Jesus rulership in heaven and the return to true worship for his faithful followers on earth.
