Now most of us are at one end of the spectrum or the other. And I suppose our native desire would be for a Christian life in which our emotions were on an absolutely even keel; and one day they will be. But that will be an even keel of prolonged ecstasy, that we will be able to cope with in resurrection bodies that were made for prolonged ecstasy! And until that happens, one of the things that God does to us in worship—and it seems to me so marvelously gracious that He has given us songs to sing that do this in worship—is to take those of us who have layers of emotion that need to be unpacked and unstarched, and He begins to set them free; and those of whose emotions at the other end of the spectrum are out of control, and He takes them and brings them into a certain kind of order and discipline by the very things we sing.
