8 and will launch again his old work of deceiving the nations, searching out victims in every nook and cranny of earth, even Gog and Magog! He'll talk them into going to war and will gather a huge army, millions strong. 9 They'll stream across the earth, surround and lay siege to the camp of God's holy people, the Beloved City. They'll no sooner get there than fire will pour out of Heaven and burn them up.
Matthew Henry's Commentary on Revelation 20:8-9
Commentary on Revelation 20:7-10
(Read Revelation 20:7-10)
While this world lasts, Satan's power in it will not be wholly destroyed, though it may be limited and lessened. No sooner is Satan let loose, than he again begins deceiving the nations, and stirring them up to make war with the saints and servants of God. It would be well if the servants and ministers of Christ were as active and persevering in doing good, as his enemies in doing mischief. God will fight this last and decisive battle for his people, that the victory may be complete, and the glory be to himself.
