And yet waiting is an essential part of the Christian life. …This is the mystery of our faith, that we are always waiting for Christ to come to us even though we believe that he has already come and that he is coming to us right now in word and sacrament. Is his coming past, present, or future? It is all three, which means that our waiting is not a matter of entering into suspended animation.
Our waiting is not nothing. It is something—a very big something—because people tend to be shaped by whatever it is they are waiting for.
