If you truly live your faith than no matter what your line of work, that faith will shine through. Your faith can't help but shape your worldview. I have a special interest in the integration of faith and art. There are many wonderful Catholic and Christian artists out there spreading the good news through their art, whether that art is visual, literary, or musical.
One group of Catholic visual artists I just read about in the National Catholic Register. Franciscan Renaissance is a group dedicated to promoting the culture of life in their work. While the website is definitely a work in progress, it does give a glimpse into the type of work these artists are creating. My favorite piece is "Heart of Mary" by Wendy McNeill, a third-order Franciscan. This painting is an icon for an upcoming pro-life tour (Future Depends on Love) which will be used as a prayer card and for the tour's banner. Some of the proceeds from the sale of the art pieces featured go to help the Franciscan Friar's of Renewal's hands-on work with the poor.
