"Have an attitude of gratitude" is one of those catchphrases fit for bumper stickers and children's books. Yet, for Christians, this is more than a catchphrase. It is a basic command of Christian life. Notice in today's Gospel reading the ten lepers who were healed by Jesus. All ten turned to Jesus in faith with their request. However, after they are healed, only one of the ten returns to thank him for answering their prayer. What lesson should we take from the story?
