How do we know the prophecies about Jesus are true?

The veracity of the prophecies concerning Jesus can be seen in their detailed fulfillment throughout the New Testament. For instance, Zechariah's prophetic mention of a king riding on a donkey in Zechariah 9:9 is fulfilled during Jesus' triumphant entry into Jerusalem. Scriptural mandates required that prophecies be tested against fulfillment, and Jesus' life, death, and resurrection align perfectly with these prophecies. This historical validation establishes that God's word through the prophets was accurate and authoritative, affirming that Jesus is indeed the promised Messiah.
