During the thousand-year reign of Christ that old serpent, the devil and Satan, has been restrained, that he might not deceive the nations and peoples during the Messianic reign.

(Revelation 20:1-3) Being released for a little season at the end of that period, he has put forth his efforts again to deceive; but now these have ended and Satan is destroyed, because God has decreed it thus.

(Revelation 20:7-10; Hebrews 2:14) Abraham, the father of the faithful, and his colleagues of like faithfulness, who have, under the supervision of the Christ, directed the people through their Millennial trial, have finished their earthly career and have been raised to a higher plane as spirit beings.

Having during that reign turned many to righteousness, they shine forth as the stars for ever and ever.

(Daniel 12:3) The earth has been brought to a condition of Edenic Paradise.
