If you didn’t like gospel music before, then let me tell you — this performance will absolutely change your mind.

Duets is a reality competition show that features famous musical mentors who search for unknown singers to duet with them as they perform in front of a live studio audience. Jennifer Nettles, of country duo Sugarland, is one of these mentors. She chose to work with a singer named John Glosson. Here, Jennifer and John show everyone how much their hard work has paid off with atruly astonishing rendition of “How Great Thou Art.”

Jennifer Nettles has one of the most beautiful and powerful voices in music today, so John definitely had his work cut out for him. Halfway through the song, the way they belt it out while perfectly blending their voices together sent chills down my spine. It’s effortlessly stunning.

“How Great Thou Art” is a Christian hymn based on a Swedish traditional melody and a poem written by Swedish poet Carl Gustav Boberg in 1885. It was ranked second — after “Amazing Grace” — on a list of the favorite hymns of all time in a 2001 survey by Today’s Christian magazine.
