I'm a 'christian' though I rarely just go out and tell people that. Our faith has been so screwed up by people who call themselves christians but act without thinking that I am almost ashamed to call myself a christian.
Rather, I'm a Christ follower :) I'm not lutheran or catholic or presbyterian or methodist. I believe in the God of the bible. Why? Definitely not just because my family is christian. None of my family is christian. I decided for myself what was true and I honestly believe that Jesus is the one and only way to escape hell. However, I DON'T believe that my faith in God is supposed to just 'keep me out of hell' and act like some kind of messed up fire insurance. The reason that I believe in God is because he shows himself in every aspect of my life. There is no way that I could possibly not believe in him.
Does that mean that my life is perfect? Ofcourse not. There are times when my life is bleak and feels worthless. I don't pretend to have the 'ideal life'. My family is poor, my father an addict, my mother practically nonexistant. However, I don't let that define me. Being a christian has helped me realize that I am worth something. I'm not just some circumstantial 'oops' factor in a world that was made accidentally by spontaneous space combustion. I am a life that has a purpose and that is loved.
Without becoming a christian, I would have traveled down the wrong path a long time ago. I have multiple learning disabilities as well as physical illnesses that hinder me from 'normal' learning and 'normal' life in many ways. Through my God though I have learned to exist with these problems and to not let them define who I am. God isn't a crutch to me, or insurance or just a 'just in case' type of thing. He is what I live for and what I will die for :)
