How do we know Christ is the promised Messiah?

According to Acts 13:32-33, it is proclaimed that God has fulfilled His promise by raising Jesus from the dead, which is a significant validation of Jesus as the Messiah. The entire Old Testament points to this fulfillment, demonstrating God's faithfulness in sending the promised Savior. Furthermore, the resurrection confirms His identity as both God and man, providing the sure mercies of David. As Scripture continually shows, the resurrection sets Him apart from all other prophets, affirming His role as the Messiah and Redeemer.
