What does it mean that God reigns over all the earth?

The proclamation that 'God reigneth' in Psalm 47 emphasizes His absolute sovereignty and authority over all things. This means that God is not only in control of the universe, but His plans and purposes are accomplished in accordance with His will. As believers, understanding God's reign instills confidence and assurance that He governs history for His glory and our ultimate good. His reign is characterized by holiness, power, and grace, reminding us that He is actively involved in our lives, leading us toward His divine purposes.
