How do we know that Jesus has authority over spiritual affliction?

The authority of Jesus over spiritual affliction is poignantly illustrated in the account of the mute man in Matthew 9:32-33. By casting out the demon, Jesus not only frees the individual from the physical restraint of muteness, but He also demonstrates His sovereignty over the spiritual realm. This act reveals that spiritual oppression stems from sin's entrance into the world, and through Jesus' work, believers witness the breaking of those chains. Furthermore, in 1 John 3:8, it's reiterated that Jesus was manifested to destroy the works of the devil. This assurance is foundational to the Gospel, showcasing that in Christ, believers have a great high priest who empathizes with their struggles and has the power to liberate them from all forms of bondage.
