Abraham bowed down with his face to the ground. But inside he was laughing, asking himself, “How on earth could I have a son at the age of one hundred? How could Sarah have a child when she is ninety?”
Really? Can a mother forget her nursing baby? Can she forget to be kind to the child she carried in her womb? Even if she could forget, I will never forget you!
Then you will say to yourself, “Who gave birth to all these children for me? My children were killed and I was unable to have more; I was exiled and thrown aside—so who brought these children up? Look, I was abandoned, so where did they come from?”
Sing for joy, childless woman, you who haven't had a baby! Shout aloud, and sing happily, Jerusalem, you who have never given birth! For the abandoned woman now has more children than the married woman, says the Lord.
By her trust in God even Sarah herself was given the ability to conceive a child though she was too old, because she trusted God who had made the promise.
