Why is Jesus Christ's fulfillment of Scripture important for Christians?

The significance of Jesus' fulfillment of Scripture is foundational for Christians as it assures believers that every promise God made is realized in Christ. As noted in Matthew 21:4, the events of His triumphal entry into Jerusalem were preordained to fulfill what the prophet Zechariah spoke. Understanding that Christ encompasses all the 'ifs' of Scripture enhances believers' faith, knowing that every requirement and expectation set forth by God finds its perfect completion in Him. This not only offers assurance of salvation but also fortifies the Christian's hope as they recognize God's unwavering faithfulness throughout history.
