No offense to any missionaries, but anyone wandering around handing out "the truth" better have some evidence to back it up with.
I really believe that everyone should be allowed to believe whatever they want.. but if you're going to go around preaching your version of reality as truth, at least be prepared to back it up with some hard evidence. Otherwise it's kinda silly and annoying.
What we have isn't "hard evidence" as such, but we simply invite people to pray and ask God if what we are telling them is true. Which proves to be a lot more effective than you might imagine.
Could you really just choose not to serve a mission? I thought it was required. I do like the idea that they do it on their own free will better though because then it truly would be an amazing sacrifice...not so much as "I'm here because my church requires me to be" but "I'm here because I want to be here"...if that makes any sense.
Although the leaders of the church say that every young man should serve a mission, at the same time they say that it shouldn't be done just for that reason, but rather that they should believe in it. Missionaries who go just because they are expected to (the pressure comes from the family usually, not the church leaders) tend to be pretty useless.
