It has always been one of my unclerical sermons to myself, that that remark which Peter made on seeing the vision of a single hour, ought to be made by us all, in contemplating every panoramic change in the long Vision we call life... "It is good for us to be here - it is good for us to be here", repeating itself eternally.
