One of the roles of a mom is to accompany her child through life, even when her patience is pushed to its limits. But we soldier on. Perhaps one of the best examples of an early saint who never gave up was the mother of the once misguided St. Augustine of Hippo.
St. Monica dug her heels in, followed her son to another country, and wouldn't give up on him. Her strength paid off when her son converted and became one of the most influential teachers in Christendom.
