Cornerstone participates in two school-wide benevolence projects annually. These projects provide students an opportunity to give to others out of the abundance God has blessed them with.

The first is Operation Christmas Child. This event (conducted by Samaritan's Purse) involves Cornerstone children (with their families) collecting small gifts for children, typically their own age, and placing them in shoe boxes. The boxes are collected for one week in mid November. After the collection week has taken place, the boxes are packed and shipped to children around the world. In 2007, Cornerstone families collected 106 boxes in one week!

The second project, Pennies for Patients, occurs in early February. As one of the Leukemia and Lymphoma Society's School and Youth Programs, it involves students collecting money for two weeks to benefit the Society's research efforts in finding a cure for leukemia and lymphoma. This year's drive will begin on February 4th and conclude on February 15th.
