The coming of God to earth in the person of Jesus Christ is the single most important event in the history of our world. But it was not an event that was isolated or removed from the Old Testament. Jesus came to fulfill the promises of the Old Testament, showing that God is faithful to fulfill all of his promises to mankind—he would bring salvation to mankind, blessing, the reversal of the curse of sin, and a King to rule and guide us, all in the person of Jesus Christ.
