How do we know Jesus' teachings have authority?

The authority of Jesus's teachings is evident in both His words and actions. In Luke 4:31-37, people reacted with astonishment at His doctrine because He preached with a confidence and understanding that set Him apart from the scribes. Unlike the religious teachers who often quoted others, Jesus spoke directly with divine authority. Furthermore, His ability to cast out unclean spirits demonstrated that His words were not only powerful but also transformative. The miracles He performed supported His teachings, proving that He was not merely a teacher but the very embodiment of Truth.
