The Universal Church of the Kingdom of God affirms a premillennial eschatology. Christ will return to earth, and at that time, Satan will be bound and removed from active influence. Christ will establish and reign over a thousand-year kingdom characterized by peace, justice, and the fullness of redemption. During this millennia reign, believers will be resurrected and glorified, and creation itself will be renewed and restored.

The premillennial framework emphasizes that the present age is characterized by the ongoing struggle between Christ's kingdom and Satan's domain. This is why spiritual warfare is necessary and urgent in the present age — believers are called to participate in Christ's victory and to advance His kingdom against the forces of evil. The millennium represents the consummation of God's kingdom, when Christ's victory is complete and His rule is universal and uncontested.

The expectation of the millennium motivates the UCKG's present missionary activity, its emphasis on spiritual warfare, and its call to believers to align themselves with Christ's kingdom now. The thousand-year reign is not distant hope but shapes present action and expectation. At the end of the millennium, Satan will be released and defeated once and for all, and eternity with God will begin for the faithful.
