Cover art for God lyrics by Nerina Pallot

She starts off saying she never understood why god is good (understandable).

But then contradicts herself in saying she believed in him? "Once my friend, I loved you as a child Kissed your face before I slept. Be in my head, and with me when I sleep" Although she doesn't say he was good then, so maybe she just believed in him as a child and then realised he was nothing when she got older.
