My favorite saint is St. Therese of Liseux. We have struggled with some of the same things and the ways she dealt with it have helped me a lot. She has such a valuable outlook on the Lord’s merciful love. I also have a great devotion to Our Lady, she is such a vital part of the spiritual life and brings us very close to our Lord.
Another one I love is St. Joseph. He is a very good example of how to be a good father and a humble, hardworking man.
