Thanks for your honesty, and I read your other comments too. But you're right... I already know this. He's a good guy. He didn't go on a mission because he was already late to decide (20), and he was in his 2nd year at the university... I know how important it is for men to go on a mission. Still, if he decided not to go because he felt he wasn't prepared at that point, I want to help him to understand better about the gospel (he reads all church material from the library app, and he knows the story of the restoration and everything, but the problem is that he doesn't feel the doctrine) I went through those same problems before. Still, I kept attending church and trying because I knew the gospel gives us something positive to live a happier life. I have a strong testimony about the church in the present. I've been reading and praying, and I see he's still trying to feel something, to gain a testimony. But that takes more time for some people to find it. I know the reason why I want to get sealed in the temple with my future exaltation. But I want to help him to understand why it is that important for him in his life. It may be because I can be empathetic toward people's feelings. I also don't want him to be alone.
But there's something true too. I tried everything, and if that doesn't change anything... well, I know what the answer is at this point. Thanks
