What does it mean that the Lord God omnipotent reigns?

The declaration that 'the Lord God omnipotent reigns' indicates His comprehensive authority over every element of existence. This assertion in Revelation 19:6 reminds believers that His reign is not passive but actively involves His providence guiding the affairs of men and nations. God's omnipotence implies that even amidst chaos, He orchestrates events to fulfill His purposes. His sovereignty assures us that, while we may face opposition and trials, ultimately, He is in control and will lead His people to victory and redemption, typified by the ultimate destruction of His enemies, as illustrated by the fall of Babylon.
