Saint Sarah is the patron saint of laughter, daughters, and gypsies. She was the wife of Abraham and the first female convert to Abraham's faith. She gave birth to Isaac at the age of 90 after angels told her in a dream that she would have a child, which made her laugh in disbelief. She is venerated for her faith and for founding the Hebrew nation through her son Isaac. The document discusses Sarah's life, miracles, and why she is a role model of faith and strength.
