In this heartwarming clip, President Obama delivers a rousing rendition of “Amazing Grace” at the eulogy for Rev. Clementa Pinckney, the pastor who lost his life in the Charleston massacre last weekend.

It’s an amazing performance by the most influential President our country has seen in the modern era. From gay rights to healthcare to being brave enough to tackle America’s racial issues head-on, it caps a landmark week for one of the greatest politicians our nation has ever seen. It’s truly inspiring to see him take such an awful tragedy and turn it into an hopeful moment of unity.
