Finding out your genealogy through websites like ancestry.com and 23andme.com is all the rage these days. People have been surprised that their DNA makeup is more from one country than another. For instance, though my aunt was born a Zimmermann (a very German name), ancestry.com revealed that her heritage comes far more from Great Britain than Germany. These sites have even led to people gathering to meet far distant relatives they did not know previously to learn more about their family history.
In the Bible people were very careful to track their lineage. In fact, almost all of Matthew 1 tracks the 42 generations from Abraham to Jesus, highlighting that Jesus is connected directly to the line of King David. Luke 3:23-38 follows the ancestry of Jesus all the way back to Adam through 77 tongue-twisting names.
Why all the emphasis on the genealogy of Jesus? The genealogy from Abraham to Jesus confirms the promise that God made to Abraham, ‘I will make your descendants as numerous as the stars in the sky and I will give your descendants all this land I promised them, and it will be their inheritance forever’” (Exodus 32:13). And the genealogy from Adam to Jesus revealed the fulfillment of God’s promise of a Savior from sin from Adam and Eve’s offspring in Genesis 3:15 when he said to the serpent; “And I will put enmity between you and the woman, and between your offspring and hers;
he will crush your head, and you will strike his heel.”
The good news for us as believers in Christ is that we may not be blood relatives of Jesus by birth, but we have been grafted into the family of God by the blood he shed on the cross for the forgiveness of sins. God’s promises of old now apply to us as well. “If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise,” Galatians 3:29 tells us. Each Sunday then becomes a family reunion when we join with our brothers and sisters in Christ to celebrate our place in the family of God. Enjoy being part of this holy heritage.
