How do we know God's sovereignty over good spirits?

The Bible refers to angels as ministering spirits sent to serve those who will inherit salvation (Hebrews 1:14). This clearly indicates that good spirits, or angels, operate under the direct command of God. Throughout Scripture, we witness instances where God sends angels to protect, deliver, and guide His people. For example, in Acts 12, an angel is sent by God to free Peter from prison, showcasing God's authority and purpose even in the manner in which He interacts with heavenly beings.
