She constantly worked to aid the poor Scotland. She encouraged people to live a devout life, grow in prayer, and grow in holiness. She helped to build churches, including the Abbey of Dunfermline, where a relic of the true Cross is kept. She was well-known for her deep life of prayer and piety. She set aside specific times for prayer and to read Scripture. She didn't eat often and slept very little so she would have more time for her devotions. She lived holiness of life as a wife, mother and lay woman; truly in love with Jesus Christ.
St. Margaret is the patron saint of Scotland and her feast day is celebrated on November 16.
