How do we know that Jesus' authority is true?

The authority of Jesus is supported by the works He performed, as noted throughout the Gospels. In John 10:25, Jesus says, 'The works that I do in my Father’s name bear witness of me,' indicating that His miracles served as divine endorsements of His authority. Furthermore, Scripture portrays Him as fulfilling prophecies and performing signs that authenticate His claims. His resurrection from the dead is the ultimate proof of His power and authority, as affirmed in Romans 1:4. Thus, the convergence of His divine works, fulfilling of prophecy, and the witness of the New Testament culminate in strong evidence of His authority as the Son of God.
