How did Jesus demonstrate His authority over demons?

Throughout the Gospel accounts, especially noted in Matthew and Mark, Jesus' encounters with demon-possessed individuals provide profound insight into His authority over spiritual realms. The healing of the mute demoniac is a clear example, where Jesus not only addresses the physical ailment but also confronts the demonic presence (Matthew 9:32-33). By casting out demons, Jesus illustrates His divine power and His role as the conqueror of evil. This authority is a critical aspect of His ministry, distinguishing Him from other religious leaders of the time, and reinforcing the belief that He is the Son of God, capable of vanquishing the forces of darkness.
