Today's reading

Today's reading is Genesis 19, part 2, and it ends with the births of two nations.

The firstborn bore a son, and named him Moab. He is the father of the Moabites to this day. The younger also bore a son, and called his name Ben Ammi. He is the father of the children of Ammon to this day.

(Genesis 19:37-38, WEB)

Reflection

Pastor Jack Graham says this is among the darkest and hardest passages to read in the whole Bible, and he insists it is here for a reason. After escaping Sodom, Lot and his daughters lived in a cave. They had lost their home, their mother and their future.

In that isolation, Graham says, fear took over. The daughters believed they would never marry or have children, so they got their father drunk on two separate nights and slept with him. From that sin came Moab and Ben Ammi, the fathers of the Moabites and the Ammonites, two nations that became thorns in Israel's side for generations.

Graham's first point is that God does not cover up the sins of the people in the Bible, even the heroes. The Bible is raw and real, and what it records is there for our teaching. Here is the lesson he draws: "Sin is never isolated. It is toxic. It infects. It spreads. It shapes the future." And he adds, "Sin will take you farther than you wanna go, keep you longer than you wanna stay, and cost you far more than you wanna pay."

Yet the story does not stop in the cave. Graham points ahead centuries to a Moabite woman named Ruth, who became the great grandmother of King David. Out of David's line came Jesus. Where Lot's daughters acted out of fear and shame, Ruth acted out of faith and loyalty, and God brought the light of the world out of a dark family line.

That is why Graham says, "In our guilt, God gives us grace." He ties it to Paul's words about not being ashamed of the gospel, because it is the power of God for salvation (Romans 1:16). Then he speaks to anyone carrying shame from their family history: "No sin is too great for God to redeem. No past, not even yours, is too broken for him to restore."

Take it with you

  • Is there a pattern of sin or pain in your family that you have been afraid to name? Bring it honestly to God today.
  • Fear drove the choices in that cave. What decisions might fear be pushing you toward right now?
  • Ruth's story began in a line marked by sin. What would it look like to answer your own past with faith and loyalty to God?

Prayer

Lord, you see the places in our families and in our own lives that still carry shame. Forgive us for the sins we have chosen, and heal the wounds we inherited. When fear tempts us to take matters into our own hands, draw us back to you. Thank you that your grace reaches even the darkest chapters, and that Jesus came to break every chain and write a new story. Write that story in us today. Amen.
