How does ancestry shape our faith?
What role does ancestry play in understanding our identity and purpose in Christ?

Setting the Scene: Luke 3:36

“the son of Cainan, the son of Arphaxad, the son of Shem, the son of Noah, the son of Lamech,”


Why This Single Line Matters

• Every name is a real person in a real timeline; Scripture records literal history, not myth.

• The verse links Jesus back to Shem and Noah, anchoring Him in the covenant line that survived the Flood (Genesis 6–9).

• It reminds us that God’s redemptive plan has always moved through actual families—broken yet chosen.


Ancestry and Identity in Christ

• We share a spiritual lineage through faith:

Galatians 3:29: “If you belong to Christ, then you are Abraham’s seed.”

Romans 4:16 shows the promise rests on grace “to all Abraham’s offspring.”

• Our adoption is legal and permanent:

Ephesians 2:19: “You are no longer strangers and aliens, but fellow citizens… and members of God’s household.”

• Because Luke traces Jesus to Noah, He represents all humanity, making His atonement universally sufficient (Romans 5:18–19).


Ancestry and Purpose in Christ

• Blessing the nations:

Genesis 12:3 promises that through Abraham “all the families of the earth will be blessed.”

Acts 3:25–26 declares this fulfilled in Jesus, sending us to turn others from wickedness.

• Continuing the priestly calling:

1 Peter 2:9: we are “a chosen race, a royal priesthood” charged to “proclaim the excellencies” of God.

• Living as image-bearers rescued in Christ echoes Noah’s post-Flood mandate to “be fruitful and multiply” (Genesis 9:1). Our purpose includes multiplication—through gospel witness and disciple-making.


Living Out Our Lineage Today

1. Celebrate the story: rehearse the biblical family tree to remember God’s unwavering faithfulness.

2. Stand firm in adopted identity: refuse the lie that background, ethnicity, or past sin defines you more than being “in Christ” (2 Corinthians 5:17).

3. Pass the promise forward:

• Teach children and new believers the sweeping narrative from Adam to Jesus.

• Model covenant loyalty in everyday relationships.

4. Extend the family: engage neighbors and nations, inviting them into the same saving lineage through faith in Jesus.
