God intervenes directly. Sarai's safety is essential to the covenant — if she stays in Pharaoh's house, the promise of a child through her is threatened. God's covenant faithfulness overrides Abram's failure. This foreshadows the Exodus: God sending plagues on Pharaoh and bringing His people out. It is a preview of the great deliverance to come.
Memory phrase: God protects His people even when they cannot protect themselves.
Talk about it: God protected Sarai even though Abram's plan had failed. What does that tell us about God's faithfulness even when we mess up?
Prayer: God, thank You that You protect me even when I make mistakes. Your faithfulness is greater than my failures.
