Sovereignty is the term the Bible uses to describe God's perfect control and management of the universe. He preserves and governs every element. He's continually involved with all created things, directing them to act in a way that fulfills his divine purpose. That's why the most stressed-out people are control freaks. They fail at the quest they most pursue. The more they try to control the world, the more they realize they cannot. Life becomes a cycle of anxiety, failure; anxiety, failure; anxiety, failure. We can't take control, because control is not ours to take.
