She said she felt like it was the ''right time'' to sing about believing in God but she didn't want to be too specific so everybody could relate to the song.
She continued: ''Not everybody believes in God, so everybody can listen to that song and take from it what they want, but I knew what it meant to me.''
Jessie thinks it's important for artists to be themselves and sing about what they want to.
She added: ''You only get one chance ... especially as an artist, I think it's so important what your life is made of.''
