But if he believe in demons also believe in God...

My Opinion

ok maybe late but yeah i also think hes depressed for a girl he try to love her but something is stopping him maybe she dosnt love him anymore so he looks faith in god but he cant find it demons also could mean he has a broken heart and the demosn are all the fears and sorrow arround the subject like shadows or demons arround and trying to find a solution or a miracle and faith in god

@FraciscoB the demons could be metaphors ... that is his demons might simply be his past events that still haunt him.

Generally the argument is that if you believe in Satan then you must believe in God ... but doesn't necessarily mean you believe in seeing God in a positive light
