What does the Bible say about the binding and loosing of Satan?

Revelation 20 describes a period where Satan is bound to prevent him from deceiving the nations. This binding occurs at Calvary, where Christ triumphed over Satan through His death and resurrection. The binding symbolizes the current age of grace, during which the gospel is preached, and the elect are called and saved. However, the Scripture warns that there will come a time when Satan will be loosed for a little season, as described in verses 7-9, to gather the nations for a final assault against God's people. This points to the reality of spiritual warfare and the ongoing influence of evil, culminating in a deceptive uprising that is ultimately defeated by God's power.
