Why is the fulfillment of prophecies about Jesus important?

The repeated phrase 'that it might be fulfilled' in Matthew's Gospel serves to remind readers of the divine authority and accuracy of God's promises. Each event in Jesus' life, from His birth in Bethlehem (Micah 5:2) to His flight into Egypt (Hosea 11:1) and His crucifixion (Psalm 22:18), aligns with detailed prophecies, reflecting not just a series of coincidences but the deliberate plan of God for redemption. This underscores God's faithful character and the certainty that He stands behind His word, providing believers with assurance in their faith.
