How do we know Christ is the fulfillment of God's promise of peace?

The New Testament confirms that Jesus Christ is the seed of David and the one who establishes peace promised in Scriptures. As stated, Christ came to fulfill the law and the prophets (Matthew 5:17), and through His sacrificial death, He reconciles sinners to God, thereby securing peace for His people. This peace is not contingent upon our actions but is based solely on Christ's righteousness applied to believers. Therefore, understanding Christ as the fulfillment of God’s promise emphasizes the necessity of looking to Him for true peace and reconciliation.
