Curse you all. I wanted to be the one to mock and question why he would post such a thing on a random internet forum
It seems more like bait to me, but you know what I always say: "don't feed the trolls, feed the dragon instead".
Realize that the missionaries you are talking to here are at the Missionary Training Center in Provo, Utah. Less than two weeks ago this kid just said goodbye to his family for 2 years to go out and serve the lord. He doesn't have the first clue what he's doing yet. He understands a few scriptures, but only because he was taught them by someone else. He has fully discovered them for himself, and therefore doesn't entirely understand them. I would hope that the next thing he does is go back to his room to study so that he knows the scripture well enough to effectively explain his interpretation to others.
A more experienced missionary would hopefully realize that such a line of conversation is ultimately useless. Our position is simple. If you ask god with a sincere heart, with real intent, and having faith in Christ he will manifest the truth of it to you by the power of holy ghost. Until that happens you will never know, and we don't have anything to talk about. If I were you I would start with the sincere heart bit.
