Those were good answers, but I just want to add that having a desire to believe is not the same thing as believing, and at least for me desiring to believe was all I had for some time and it was not enough. I wanted the church I grew up with and honestly loved to be true and I wanted it to make sense and I wanted it to all fit together and work for me and my life, but in fact that is not how things went. It is a great sentiment to say one should try to believe and want to or else they won't, but by the same token wanting to believe does not necessarily lead to belief. The other thing I wanted to say was that I'm a little sad the first writer felt (s)he needed to be anonymous. There should be no shame (although obviously there can be and often is) in struggles with faith and trying to learn about one's faith. I was embarrassed every time I wrote about my disbelief, but putting my name to it was cathartic and friends would occasionally email me and be friend-like because they saw I was struggling. Obviously that is a personal choice, and maybe anonymous readers don't care if anonymous writers add that extra layer of anonymity, but yeah.
Oh, and the other other thing I wanted to say is that this soon-to-be-missionary will hopefully be able to better understand members and investigators who are having a hard time deciding whether or not the church is true (or true for them).
[ETA: Sorry this was kind of just a rant without anything to really contribute. I'm not trying to be mean or anything, promise.
