What does the Bible say about the power of Jesus to cast out demons?

In Luke 11:14-23, we see a profound example of Jesus casting out a devil from a man who was mute, illustrating His supreme authority over the spiritual realm. As He performed these miracles, some onlookers accused Him of casting out demons by the power of Beelzebub, the chief of demons. However, Jesus argued that a kingdom divided against itself cannot stand, implying that His power was divine in nature and evidence of God's kingdom breaking into the world. This incident underscores the reality that Jesus' miracles were not mere acts of kindness but declarations of His identity as the Messiah and Lord over all spiritual darkness.
