What does it mean that God reigns, according to the Bible?

The assertion that God reigns is a central theme throughout scripture, asserting His ultimate sovereignty in all matters of life, creation, and salvation. In Isaiah 52:7, the proclamation that 'Thy God reigneth' reveals not only His control over the universe but also His intimate governance in the lives of His people. This means that nothing occurs outside His will; He governs every aspect of existence, including the spiritual realm. For Christians, this reign offers assurance that God is in complete control, bringing comfort amidst chaos and trials.
