How do we know Jesus' works testify that He is the Son of God?

In John 5:36, Jesus Himself points to His works as greater testimony than even that of John the Baptist. The miracles He performed—healing the sick, giving sight to the blind, and ultimately laying down His life—demonstrate His authority and mission from the Father. Jesus did not merely make salvation available; He completed the necessary work for redemption by paying the penalty for sin. His actions affirm the divine nature of His ministry and establish Him as the true Son of God who accomplishes what He sets out to achieve.
