Ich glaube an

I already knew the verb glaiuben (to believe) but today I learnt two new things about it:

ich glaub or ich glaub' is a slang way of saying ich glaube.

If you want to believe in something you say 'ich glaube an.....'

mein gebet = my prayer

I haven't been able to find the lyrics to this online yet so not sure what it is that he's been praying about.
