Yet, I think it is a legitimate question to ask why a young man who is 20 or over has not served a mission, if you are young women considering whether or not to date that young man. The questioner said that he didn't go at first for "musical purposes." Really, I thought musical talent wasn't a requirement for a mission.
I don't buy the argument "he didn't feel like it was right for him. He didn't think he was in the right place in his life to be able to put his heart into it." Right, like the rest of us didn't have to struggle with gaining a testimony of going on a mission. It is a young man's duty, and I would worry that such a man might marry my daughter and decide one day that being faithful to her was not right for him at some future time. That he wasn't then at a place in his life to be able to put his heart in it. Good grief. Buck up. Be a man. Take responsibility for your life.
"If the choice to not go on a mission was because of worthiness issues, as long as those have been/are being worked through, I don't see a problem." I do. Part of the repentance process, working through the issue, is to make restitution. So, he made some mistakes, feels sorry for them now, and is now worthy. So now go on a mission. If his mistakes were so serious that they will no longer let him go on a mission, or he waited so long to repent that he is too old to go, then I see a red flag.
Of course, we should all be charitable, forgiving, and non-judgmental. I wouldn't ask someone why he didn't serve a mission. It is none of my business. And I would assume the best. But the question was addressed to the women of the Board about dating someone who chose not to serve a mission. I'm glad to learn of their opinions. I'm just saying that I hope my daughters do ask such questions, because it is their business if the young man is interested in them. And I hope they see through the flimsy excuses for disobeying God.
