By the Grace of God (song)

"By the Grace of God" is a song by American singer Katy Perry from her fourth studio album, Prism (2013), included as the standard edition's final track. The song, a Christian pop record, was written and produced by Perry and Canadian record producer Greg Wells, and was recorded in November 2012, at Rocket Carousel Studios, based in Los Angeles, California. It was conceived following Perry's divorce from English actor and comedian Russell Brand. This initially made Perry consider making a "darker" album, but instead was channeled into the song. Throughout its autobiographical lyrics, Perry is depicted finding her strength and standing up for herself.

The track was first unveiled at Perry's headlining set at the 2013 Apple Music Festival. Upon the release of Prism, "By the Grace of God" received generally positive reviews from music critics, who appreciated its vulnerability and picked it as one of the musical highlights from the album. Following the digital sales of Prism, it charted at number 179 in the United Kingdom and number 77 in South Korea, alongside charting at number 70 on the Canadian Digital Song Sales chart. It also peaked within the top 10 of the Billboard Bubbling Under Hot 100 Singles chart in the United States, where it also charted at number 71 on their Digital Song Sales chart.
