I've come to know all too well that sometimes religion chooses you. And, when such a thing happens, you better stand up and accept the offer. Free will goes so far but every now and then we'll get a nudge.
Just don't take anything too seriously.
Also, i feel it's best not to actually settle into anything until you've grown up and have a much better understanding of yourself and what you want, from life and the world around you. Not that you can't change your mind, but let's face it: who wants to look stupid in front of a deity?
Also, no religious tattoos!
