They also have a food pantry that serves many homes with food boxes. They have a visitation team that ministers to the community in the comfort of their own homes. They have also established a childrens ministry that focuses on building relationships with local children by bussing them in for Bible study. During the summer they manage the Learning Center. There are four sections to the learning Center; math, reading, computers, and library.
