But whatever may be the variety in regard to the mere externals of our lives, how true it is about us all that even the most familiar duties of to-day are not quite like the same duties when they had to be done yesterday; and that the path for each of us--though, as we go along, we find in it nothing new--is yet an untrodden path! For we are not quite the same as we were yesterday, though our work may be the same, and the difference in us makes it in some measure different. But what mainly makes even the most well-beaten paths new at the thousandth time of traversing them is our ignorance of what may be waiting round the next turn of the road. The veil that hangs before and hides the future is a blessing, though we sometimes grumble at it, and sometimes petulantly try to make pinholes through it, and peep in to see a little of what is behind it. It brings freshness into our lives, and a possibility of anticipation, and even of wonder and expectation, that prevents us from stagnating. Even in the most habitual repetition of the same tasks 'ye have not passed this way heretofore.' And life for every one of us is still full of possibilities so great and so terrible that we may well feel that the mist that covers the future is a blessing and a source of strength for us all. Our march through time is like that of men in a mist, in which things loom in strangely distorted shapes, unlike their real selves, until we get close up to them, and only then do we discover them. So for us all the path is new and unknown by reason of the sudden surprises that may be sprung upon us, by reason of the sudden temptations that may start up at any moment in our course, by reason of the earthquakes that may shatter the most solid-seeming lives, by reason of the sudden calamities that may fall upon us. The sorrows that we anticipate seldom come, and those that do come are seldom anticipated. The most fatal bolts are generally from the blue. One flash, all unlooked for, is enough to blast the tree in all its leafy pride. Many of us, I have no doubt, can look back to times in our lives when, without anticipation on our parts, or warning from anything outside of us, a smiting hand fell upon some of our blessings. The morning dawned upon the gourd in full vigour of growth, and in the evening it was stretched yellow and wilted upon the turf. Dear brethren, anything may come out of that dark cloud through which our life's course has to pass, and there are some things concerning which all that we know is that they must come.
