I love this song. The tune was written by Jonathan Hamilton, son of Ron and Shelly Hamilton (of Patch the Pirate fame, for those who know of him.) Jonathan died as a young adult, and Chris Anderson was commissioned to write this hymn to Jonathan’s melody. It’s sung by Jonathan’s sister and brother-in-law, Ben and Tara Farrell. The words are in the video, but you can see them all in one piece here along with some of the thinking behind the words.
