Shining in Daniel 12:3

Several years ago I heard in a sermon (from John MacArthur I think) that, corresponding to Daniel 12:3 where it says those who have insight will shine like stars, that our ultimate reward in heaven will be the capacity to radiate the glory of God in all eternity. It was something like that. I have heard the teaching two other times, perhaps from preachers who got it from MacArthur or his source. This idea has captivated me for quite a few years. Can any of you help me find more information on this topic and possibly help in understanding whether this is a valid idea? Thank you.
