What does the Bible say about God's control over evil spirits?

The Scriptures demonstrate that God's sovereignty extends to all beings, including evil spirits. 1 Samuel 8:10 shows that God can send an evil spirit to fulfill His divine plans, showcasing His ultimate authority over all creation. Despite our limited understanding of how this works, we must recognize that God's providence governs all things without compromising His holiness or nature. Romans 8:28 reassures us that all things work together for good to those who love God, affirming that even the actions of evil spirits are ultimately under God's directive power.
