baptism

i want to get baptised. like.... really really really want to be baptised. like... theres a little voice that keeps screaming in my ear "its time"

problem: my parents wont let me. i dont want to do it without their permission. but how can i explain this to them when i dont even know how to put this into words? how i can i get them to see my side? how can i be understanding of their side and show them that i do care what they think, without giving up on what i beleive? how can i get them to at least let me do it? how?

so please pray for me guys, im going to try to talk to them about it.
