For JWs, there is a two-step process for committing yourself to God. Before you get baptized in public, you are supposed to privately "dedicate" yourself to God in prayer.
I was a child who knelt in the corner of my room after completing my final "interview" of questions from an elder. I tried to be sincere, but I was aware I had no emotional currency (I was only 13, give me a break!).
Later on, I realized that my "dedication" was void as I felt no personal relationship to God. It was this vacuum that lead me to expose myself to non-JW beliefs and my eventual discard of all JW precepts. My current spiritual fulfillment have nothing to do with that naive "dedication."
When I ask other JWs this question (especially the ones baptized as youth) I get very similiar answers. How about you?
