Genealogies can be found in both the Old and New Testaments. They are subtle yet stubborn proofs of the Scriptures’ historicity and are essential to proving the faithfulness of God in keeping His Messianic promises to Abraham, Isaac, Jacob, Judah, and David (Matthew 1:1-17).
With the coming of the gospel, “Who’s your Daddy?” has a different significance. Because it does not matter whether you are Jew or Gentile (Romans 10:12), your physical genealogy is immaterial.
Your spiritual paternity, however, is of supreme importance. The answer to the question of “Who’s your Daddy?” matters, because “when desire has conceived, it gives birth (apokueo) to sin (James 1:15) and because “He brought us forth (apokueo) by the word of truth” (James 1:18).
Spiritually speaking, “Who’s your Daddy?” has only two possible answers—Satan or God. Without the new birth, you cannot enter or see the kingdom of God (John 3:3, 5).
