She was pushing 100 years old and God made a specific promise to her. He told Sarah that within a year she was going to be a mom—even though she was barren and well beyond the normal age for motherhood. Upon hearing this, she laughed. Then after being confronted by God about her response she denied it; but God persisted, “No, but you did laugh.”
God made a great promise but Sarah couldn’t believe it. She laughed in the face of such an unbelievable promise.
