1 Peter 1:8 talks about “joy unspeakable” and “full of glory”. Suppose you had experienced this “joy unspeakable”, and had to explain it to someone else. How would you do that? Well, about the best way you could put it would be that it is, in fact, “joy”, and, it’s so incredible, it’s “unspeakable”, so that words do not even seem to do it justice. That would be about it. You could, perhaps, get a few more adjectives in there. It was so “glorious”. But, unless someone else had even seen “glorious”, they wouldn’t get it. You would be more or less stuck, unable to explain it to them.
