Hillsong United recently shared what they call a life-changing moment when they visited an inmate who wrote to them from Folsom State Prison in California. Inmate Lothar Preston sent them a letter to share how much they have inspired him, so this summer the band visited the prison and performed "How Great Thou Art," "Amazing Grace," and "Oceans" in a packed prison chapel. Hillsong United shared their feelings about the experience on their YouTube page and explained why they wanted to visit the prison. They say "This guy has been behind bars for a very long time but through the music that we've been able to create, it's basically led him to Jesus." See the inspiring video.
