What does the Bible say about fulfilled prophecies?

The fulfillment of prophecy is significant in biblical theology, particularly regarding Jesus Christ. In Matthew 21, we see several Old Testament prophecies that culminate in Christ's entry into Jerusalem, validating His identity as the Messiah. These include the praise from children in the temple, fulfilling Psalm 8, and His lowly entrance on a donkey, as foretold in Zechariah 9:9. Such fulfilled prophecies serve as evidence of God's faithfulness in His promises, showing that He is sovereign over the course of history and has orchestrated events to point to Jesus as the ultimate Deliverer.
