When God says, "Comfort! Comfort my people," he’s not instructing us to work up, in our own power, a level of comfort in our heart or spirit. He doesn’t offer us a commodity called comfort—He is comfort itself. When God shows up, comfort shows up, too. This is what He is—though, of course, it’s not all He is—which may help us see why the Lord’s mere presence is sufficient to change everything.
