Justin Moore had the crowd at the 2015 iHeartRadio Country Festival reaching for their cell phones and lighters during his touching song "If Heaven Wasn't So Far Away."

The song was released as the debut single from his 2011 record, Outlaws Like Me, and Moore's performance during the event was especially touching because he dedicated the song to the Americans who have lost their lives fighting for their country.

"I want to send out this song to all the military men and women who never made it back home for us," he said from stage.

Moore told everyone in the crowd stand up and hold up lighters, flashlights, cell phones -- anything they had with them that lit up.

"Ain't nobody too cool to do this for our military," he announced, encouraging fans to help "make this the most beautiful place on Earth."

Then, Moore introduced his song by saying, "Man, if heaven weren't so far away, I might just go up there and sing this to them myself."

Not only was Moore's performance absolutely beautiful, but the Frank Erwin Center, where the show was held in Austin, Texas, was 100-percent stunning during the song. Tiny beams of light were everywhere, and the arena looked like it was a night sky full of shimmering stars.

At the end of Moore's performance, he hung his hat up on the mic stand, stood back and blew a kiss heavenward.

The 2015 iHeartRadio Country Festival featured artists like Dierks Bentley, Darius Rucker, the Band Perry, Little Big Town and many more. The event took place on May 2 and aired Wednesday night (May 27) on NBC.

Moore is currently working on his fourth studio album.
