Studying one's religion from the view of demonstrating it's validity often causes people to leave the religion. You're a bit young, but seem reasonably mature. If they ever convince you to go to one of their meetings (a.k.a. church), and you "feel" something, note that it's a normal psychological response to the stimuli they present you, and not supernatural in any way. If you want to feel those feelings, I recommend a similarly styled nonChristian music concert (i.e. if you like the way the charismatic meetings feel, go to a rock concert).
