"Amazing Grace" was the first solo that Kelsea Ballerini ever sang. On Friday morning (July 17), she performed the inspirational song to comfort those in Chattanooga affected by the shootings at a naval reserve center and a military recruiting center.

During her appearance on Fox & Friends, the Knoxville, Tenn., native, showed her support for the city of Chattanooga and the loved ones of the four Marines who were killed and the several people who were injured -- including a police officer, a Marine Corps recruiter and a sailor -- during Thursday's (July 16) tragedy with her stirring performance.

"I think it's important to show our support and show our love so they can feel it," she said on the show.

Ballerini's vocal aptitude was on full display, but more than that, the heart behind her performance was deeply empathetic, hopeful and moving. As she sang, viewers sang along, smiled and closed their eyes, obviously affected by the moving lyrics.

The "Dibs" singer also supported the city on social media, tweeting, "Sending love and prayers to my friends in Chattanooga. #NoogaStrong."

Other country stars also sent their thoughts out, including Craig Morgan, who writes, "Our thoughts and prayers go out to all in Chattanooga dealing with this horrible situation."

Ballerini is currently on fire on the country music charts: Her debut single "Love Me Like You Mean It" broke a record when it recently reached No. 1. The tune is from her debut record, The First Time, which released May 19 on Black River Entertainment.
