Now the Lord was gracious to Sarah  as he had said, and the  Lord  did for Sarah what he had promised.   Sarah became pregnant and bore a son  to Abraham in his old age,  at the very time God had promised him.   Abraham gave the name Isaac   to the son Sarah bore him.   When his son Isaac was eight days old, Abraham circumcised him,  as God commanded him.   Abraham was a hundred years old  when his son Isaac was born to him. Sarah said, “God has brought me laughter,  and everyone who hears about this will laugh with me.”   And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”  Genesis 21:1-7 While Abraham laughed in shock, Sarah laughed in unbelief when they were told they would have a son. "When Abrahan was one hundred years  old, Sarah had a baby boy, Isaac. Sarah held Isaac and her laughter was changed to joy to the heavens. "God has brought me laughter!" This story teach
