I was raised as a Christian. I had some struggles with the reality of it all, until my faith was solidified all of a sudden.

But since then, I had gradually slipped away from the church. What got me to come back was Basic Training. It was probably the single worst experience of my life. Basic Training isn't the same for everyone; ours was worst than most.
It was good, though, because it was a huge religious revival for me. It became clear that God puts us through (seemingly) terrible situations and experiences because he is making us into the people he needs us to be.

I've been strong in my faith ever since, although I struggle with my sin like everybody.
