What does the Bible say about Satan being loosed?

Revelation 20:7-10 describes a time at the end of the gospel age, when Satan will be loosed from his prison after being bound for a thousand years. The Apostle John reveals that this release serves God's sovereign purpose, allowing Satan to go out and deceive nations, specifically represented by Gog and Magog. These nations symbolize the collective enemies of God and reveal Satan’s continuing role as the master deceiver. Ultimately, this chaos orchestrated by Satan under God’s decree leads to a decisive battle against the Church, where Christ triumphant will never be defeated.
