Read: Genesis 12, 17
I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed. (Genesis 12:3 ESV)
God said, No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. (Genesis 17:19 ESV)
I see him, but not now; I behold him, but not near: a star shall come out of Jacob, and a scepter shall rise out of Israel; it shall crush the forehead of Moab and break down all the sons of Sheth. (Numbers 24:17 ESV)
The scepter shall not depart from Judah, nor the ruler's staff from between his feet, until tribute comes to him; and to him shall be the obedience of the peoples. (Genesis 49:10 ESV)
The book of the genealogy of Jesus Christ, the son of David, the son of Abraham. Abraham was the father of Isaac, and Isaac the father of Jacob, and Jacob the father of Judah and his brothers, (Matthew 1:1, 2 ESV)
Abraham is often called the father of faith. Rightly so. God hand picked him to begin the family line of the Jews, and specifically the Messiah. Abraham believed in God's promise that he would have a son, even in his old age, and God saw his faithful disposition as righteousness.
Jesus fulfilled God's promise to Abraham. He is the blessing to the whole world. He is the embodiment of God's everlasting covenant. Jesus is the star and scepter rising out of Israel. The promised son rising from a promised people to deliver God's promised redemptive work to mankind. The rule is his, the glory is his, and the effort is his alone. What an amazing portrait the Bible paints across history to show God's blessed work to free his people from the clutches of sin and death.
Just as Jesus is the promised son, so are those who have been saved the promised sons of Father Abraham. A work of faith that reaches across millennia to prove God's prophetic grace for all mankind.
