How do we know the authority of Jesus' teachings?

The authority of Jesus' teachings stems from His divine nature as the God-man and mediator between God and humanity. As noted in Luke 24, after His resurrection, Jesus opened the understanding of His apostles about the Scriptures, demonstrating that He alone has the power to reveal truth. Additionally, His unmatched teaching style was recognized by those who heard Him, leading to amazement at His wisdom and insights. This authority is foundational for Christians, highlighting that His words are not merely suggestions but divine commands to be followed.
