Many young adults work for non-profit organizations and other industries that focus on human concerns. Consider volunteering or simply connecting with these young adults to help you plan a community service event led by them. Invite them to your parish for lunch or to check out your evening Mass. Or even invite young adults to make a post-Mass announcement about their work and their need for volunteers. If one of the young adults in your group works at a non-profit, ask them to invite their co-workers so the group can learn about the different parts of a non-profit.
