Sheryl Crow - I Shall Believe Lyrics Meaning

I have seen her 6 times live so she had said at a concert in Ottawa that this song was about her faith in God, plain and simple..you would think that the lyrics are clear as water on that lol..and in my favorite song by her 'the difficult kind' it's about her ex that wanted her to leave the music industry for his church beliefs..thankfully for all of us she pursued her dreams..that she mentioned at the 2004 concert in Atlantic City and for any of you that were there that night you will remember her words..she said 'such a pretty song about such a stupid jerk' lolol
