From the last post we see that after Jacob’s warring with Essau in the womb of Rebekah, Jacob now must war with God for heeding his mother and stealing the birthright that would lead to the Messiah. His war with the Angel of God left him with a new name, Israel, and an affliction. Often needed to break the pride of those destined to be united to God, the mark of Christianity. So that no one may boast. Witness how the story of the betrayal, burial, and resurrection of Christ the Messiah was subsequently foretold in the story of Israel’s son Joseph and his betrayal, burial, and reemergence (Genesis 37).
From this point the People of God urge on the coming of the Messiah, the day for God’s answer to Abraham that He will provide the Lamb of sacrifice. So that God Himself will offer up His own Blood for man. Witness how Moses emerges from purgatory and Elijah from his hiding place to urge Jesus on to His crucifixion at the mountain of the Transfiguration (Matthew 17). The dream of Jacob is fulfilled. Heaven has opened up.
The lineage cannot boast but in Christ the Messiah.
LUKE 3:8. Produce fruit in keeping with repentance. And do not begin to say to yourselves, ‘We have Abraham as our father.’ For I tell you that out of these stones God can raise up children for Abraham.
And how could God be conceived in the flesh without the boast of parents? Witness Joseph’s humiliation from the virginal conception of Mary (Matthew 1). But to eternally protect the incarnation of our Lord from the boast of lineage, God reached back before the fall of man that came from Adam’s sin of pride. To create the most exquisite creature every created and ever will be. Who will never boast but in God and His grace, but in whom we all can be proud. Who alone has the grace to undo the knot of pride tied by Rebekah.
