Hmm. I wouldn't say I have a "faith" per say.
Put simply I believe there is 'something' bigger than us. And that's as far as I got!
I'm not even entirely certain about the whole concept of God. That's not to say I don't think (S)He could exist. I've even been known to have a number of chats. I just think its the "name" I'm uncomfortable with. Maybe its all the connotations over the years. Maybe its that although I understand "personifying" makes it 'easier' and 'more real' for us "mere mortals" to understand I think for me it actually takes something away.
I've found myself frequently saying "The Universe" and I think that works for me. Maybe again because of the whole "something bigger than us" thing and the Universe is pretty freaking huge! But by that I mean "The force that is greater than us" - but that just sounds too Star Wars-y! :D
As a teenager the belief system that appealed to me most was Wicca/Paganism. As most teenage girls are the 'magic' intrigued me but it was more than that. It was the whole belief that everything is connected, that what you put into the world will come back on you. (3 -fold is debatable in my opinion though) But definitely 'what goes around comes around.' To be honest the God/Goddess iconology and belief again didn't sit right and that's why I stopped reading more into it.
So even when things are looking REALLY shitty I do try and remind myself that everything happens for a reason.
When someone needs prayers or thoughts I try and think on it as sending positive energy towards them into the Universe. Sometimes I will literally verbalise that with a conversation with God/The Universe/The Fates etc etc. Same goes for if I need it, or I need someone to be watched out for.
And I always say Thank You. Because at the end of the day if someone helps you out, or if your asking for their help...its only polite to thank them for it :)
PS: Oh my goodness...could I have used more of these? "..."???
