The

Devil has been sinning from the beginning.—1 John 3:8.

“At the revelation of the Lord Jesus from heaven with his powerful angels,” all “who do not know God and those who do not obey the good news about our Lord Jesus” will be destroyed. (2 Thess. 1:6-10) When John saw that same event in vision, he described Jesus and the angelic heavenly armies as going forth on white horses in order to carry on war in righteousness. (Rev. 19:11-14) John also “saw an angel coming down out of heaven with the key of the abyss and a great chain in his hand.” This is none other than the archangel Michael, who will bind the Devil and hurl him—and evidently the demons—into the abyss. They will be released briefly at the end of Christ’s Millennial Reign when perfect mankind will experience a final test. Thereafter, Satan and all other rebels will suffer destruction. (Rev. 20:1-3, 7-10) All rebellion against God will have been removed.
