How do we know Jesus is who he says he is?

Jesus's identity is confirmed through both His resurrection and the prophecies that foretold His coming. In John 20:20, the disciples recognized Him after His resurrection when He showed them His hands and side, providing irrefutable evidence of His identity. The fulfilled prophecies surrounding His life, death, and resurrection support the truth of who He claimed to be—the Messiah. Additionally, the transformation in the lives of His followers after His resurrection highlights His divine authority and the power of the Gospel.
