How is Jesus the Fulfillment of God's Promises?

Last time, we said the Last Days were ushered in by the death, resurrection and ascension of Jesus, and by the outpouring of the Holy Spirit at Pentecost. These pivotal events changed history and ushered in the Last Days because God had fulfilled all of His promises in Jesus, and the only thing remaining was for Jesus to return and consummate His kingdom.

But what makes Jesus so great? What makes His coming and His triumph the beginning of the Last Days? These opening verses of Hebrews 1 tell us five things about Jesus that make Him supreme, the definitive One, the One who alone could fulfill all the purposes of God.
