Catholic Public Domain Version
Genesis 21:2
“And she conceived and gave birth to a son in her old age, at the time that God had foretold to her.”
Verse Explanation
A saved explanation for Genesis 21:2.
Plain-language explanation
Sarah, though very old, becomes pregnant and gives birth to a son. The verse emphasizes that this happened exactly when God had promised it would.
Catholic context
Many Catholics understand this as a sign that God’s word is trustworthy and that He can bring new life in places that seem “too late.” The promise to Abraham and Sarah is fulfilled through God’s providence—faith is rewarded in God’s timing, not only in human expectations.
Historical background
In the story, Abraham and Sarah have waited a long time for the fulfillment of God’s promise of descendants. Aging and barrenness (as people would have seen it) made the promise seem impossible from a human standpoint, so Isaac’s birth highlights God’s power to act beyond natural limits.
Reflection
It can be tempting to measure God’s promises by our timelines. This verse invites us to remember that God’s faithfulness does not depend on our sense of timing, and that He can renew hope when circumstances look closed.
Practical takeaway
When you feel “too late” or uncertain, bring the situation to prayer. Hold onto God’s promises, and ask for the grace to keep trusting—especially when progress is slow.
Prayer
God of faithful promises, thank You for the hope You renew in Your time. Strengthen my trust when I cannot see results yet. Help me believe that You can make something new grow even in “old age” and seemingly impossible moments. Amen.
