1-about 10: Enjoyed reading my children's bible, went to church occasionally with family, and participated in some Sunday School and Neighborhood Bible School. Got my first real bible at age 8, which I still have to this day (and it's in decent condition, the book of revelation has come off the binding but that's about it).
about 10-graduation from high school: Developed some genuine doubts in my faith as my parents lost some interest in it and I learned about the theory of evolution in my public school courses. Never lost my faith completely, but it basically got to a point where it was basically "Yeah, I think God exists, but honestly *shrug*". In High School and as I prepared for College, my focus was Academics and Band [trumpet]. God was not a focus. I sought to justify my social conservative views through secular means rather than using the bible as an ultimate crux in those matters.
College: Massive resurgence in my faith. Was essentially recruited into a college ministry, and though many in it are more conservative in faith than I'll ever be or become, it was what I needed to put God back into my life. I had "connections" to God again, and that was what I needed to regain interest in the bible, come to a satisfying answer on creationism vs evolution (if you look up "progressive creationism", that's basically my position), and solidify my trust in Jesus for Salvation. I purchased two large study bibles during these years to replace my aging grade school bible.
Now: While I don't have the luxury of my college connections anymore, my faith is solid, I read theology books from time to time (this is what I'm currently reading:
