Christian country singer Carrie Underwood catapulted to fame after joining the singing competition "American Idol" and winning its fourth season. During the show's Grand Finale on Thursday, the singer came back and delivered a powerful rendition of her popular faith-based song "Something in the Water."

The song tells the story of a person coming to faith in Jesus Christ, CBN News reports. It was written by Underwood, Chris DeStefano and Brett James, and was produced by Mark Bright.

After her performance, Underwood raised her hands to the sky and proclaimed, "Praise the Lord!"

The song, which is part of her "Greatest Hits: Decade #1" album, has a special spot in Underwood's heart. "It's really kind of a joyous, uplifting song about changing your life for the better and kind of having that 'a-ha' moment, to waking up and your life being different from that moment forward," she earlier said of the song.

Meanwhile, DeStefano told Taste of Country that it was such a blessing to be a part of the team that created the song. He knows it is so rare for Christian music to make it big mainstream, but "Something in the Water" managed to do so despite having a strong Christian theme.

"It's very humbling to be part of it," he said. "One of the things that's been really exciting for me — I know it sounds crazy — is just reading tweets, and seeing how it's affecting people directly. You're able to really see people's emotions as they're writing on Twitter. It's incredible that it's having such a powerful effect on people. As a songwriter, that is all you can hope for, is to affect people and touch people, and make a difference in their lives, in small ways and big ways."
