Why does Lily want to touch the statue of Mary so bad?

I think Lily wants to touch the Mary statue because she wants her to accept her. She is afraid that no one will accept her because of what she did in the past. She thinks that if she touches Mary's heart then Mary will always be on her side. Lily though, was also afraid to touch the black Mary because she also was worried that she wouldn't accept her. Lily had to get out of the past though. She needed to stop thinking about her regrets and just live her life. She did not need to touch the Mary statue because the black Mary was always with her. She lived inside everyone.
