1 Nephi 1:8 -- Singing praises

At the end of the verse Lehi sees "God sitting on his throne, surrounded with numberless concourses of angels in the attitude of singing and praising their God." That kind of a scene has been hard for me to imagine at times. As I thought about it, I remember times when the prophet has come to speak and everyone spontaneously sang "We Thank Thee Oh God for a Prophet" as he entered the room. I was there to witness that scene and it was totally natural to do. I guess I now envision angels singing praises to God being somewhat similar, although it is on a much grander scale.
