Will we know him?

I just read 3 Nephi 11. When the Lord calls for Nephi I get the impression that he wasn't surprised by seeing the Lord whereas the other people kind of were. Does that make sense? I guess I just get the feeling from reading 3 Nephi 11:18-20 that Nephi knew the Lord very well.

I know you're probably thinking, "Duh Chuck! He's a prophet, of course he knows him!" But it just made me wonder how well I'll know him when I see him again. Of course I think that to some degree we'll all know him won't we. What do you think?
