season we shall reap if we faint not.' There is 'a time for weeping and a time for laughing, a time for building up and a time for casting down.' It is the same thought of life, and its successive epochs of opportunity never returning, which finds expression in the threadbare lines about 'a tide in the affairs of men, which, taken at the flood, leads on to fortune,' and neglected, condemns the rest of a career to be hemmed in among creeks and shallows. Through all the variety of human occupations, each moment comes to us with its own special mission, and yet, alas! to far too many of us the alternations do not suggest the question, what is it that I am hereby called upon to be or to do? what is the lesson that present circumstances are meant to teach, and the grace that my present condition is meant to force me to cultivate or exhibit? There is one point, as it were, upon the road where we may catch a view far away into the distance, and, if we are not on the lookout when we come there, we shall never get that glimpse at any other point along the path. The old alchemists used to believe that there was what they called the 'moment of projection,' when, into the heaving molten mass in their crucible, if they dropped the magic powder, the whole would turn into gold; an instant later and there would be explosion and death; an instant earlier and there would be no effect. And so God's moments come to us; every one of them--if we had eyes to see and hands to grasp--a crisis, affording opportunity for something for which all eternity will not afford a second opportunity, if the moment be let pass. 'The times went over him,' and your life and mine is parcelled out into seasons which have their special vocation for and message to us. How solemn that makes our life! How it destroys the monotony that we sometimes complain of! How it heightens the low things and magnifies the apparently small ones! And how it calls upon us for a sharpened attention, that we miss not any of the blessings and gifts which God is meaning to bestow upon us through the ministry of each moment! How it calls upon us for not only sharpened attention, but for a desire to know the meaning of each of the hours and of every one of His providences! And how it bids us, as the only condition of understanding the times, so as to know what we ought to do, to keep our hearts in close union with Him, and ourselves ever standing, as becomes servants, girded and ready for work; and with the question on our lips and in our hearts, 'Lord, what wouldst Thou have me to do? and what wouldst Thou have me to do _now_?' The lesson of the day has to be learned in a day, and at the moment when it is put in practice. II. Another thought suggested by this text is, the Power that moves the times.
