Experiencing Joy

C.S. Lewis called those moments of intense longing for something more, "Joy." But he made an additional comment that sheds some light, perhaps, on the struggles of Christians to experience it.

He says that if you're walking, lost in the woods, and you happen upon a signpost pointing you toward the road, there will be a considerable clamor as you excitedly examine it. But once the road is found, with periodic signposts pointing toward the destination, they become less extraordinary and exciting.

I'm not sure how to process that, honestly.
