Carrie Underwood has never shied away from publicly expressing her deep Christian faith, and her new song, 'Something in the Water,' is a perfect example.

The song talks about the importance of baptism and conversion as means to changing your life: “There’s somebody saying what I’m saying to you / Opened my eyes and told me truth / He said just a little faith and it’ll all get better / So I followed that preacher man down to the river and now I’m changed / And now I’m stronger."

The song ends with Underwood singing a portion of 'Amazing Grace.'

"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 said during a recent appearance on the 'Today' show.

The superstar doesn't worry that speaking out about her faith will alienate her fans.

“Country music is different. You have that Bible Belt-ness about it," she said in 2012. "I’m not the first person to sing about God, Jesus, faith (or) any of that, and I won’t be the last. And it won’t be the last for me, either. If you don’t like it, change the channel.”

'Something in the Water' will appear on Underwood's upcoming 'Greatest Hits: Decade #1,' which is set for release on Dec. 9.
