How do we know Jesus is the true testimony of God?

The truth of Jesus's identity as the Son of God is substantiated by His miraculous works and the prophecies fulfilled in Him. John 3:32 states, 'He bears witness to what He has seen and heard, yet no one receives His testimony.' This highlights not only the rejection faced by Jesus but also emphasizes that those who accept His testimony affirm that God is true. The fulfillment of Old Testament prophecies, His miraculous signs, and the divine nature of His teachings lend credence to the claim that He is indeed God's final and ultimate revelation.
