The inmost meaning of this Psalmist's desire is that the consciousness of God shall be diffused throughout the whole of a man's days, instead of being coagulated here and there at points. The Australian rivers in a drought present a picture of the Christian life of far too many of us--a stagnant, stinking pool here, a stretch of blinding gravel there; another little drop of water a mile away, then a long line of foul-smelling mud, and then another shallow pond. Why! it ought to run in a clear stream that has a scour in it and that will take all filth off the surface. The Psalmist longed to break down the distinction between sacred and secular; to consecrate work, of whatsoever sort it was. He had learned what so many of us need to learn far more thoroughly, that if our religion does not drive the wheels of our daily business, it is of little use; and that if the field in which our religion has power to control and impel is not that of the trivialities and secularities of our ordinary life, there is no field for it at all. 'All the days of my life.' Not only on Wednesday nights, while Tuesday and Thursday are given to the world and self; not only on Sundays; not for five minutes in the morning, when I am eager to get to my daily work, and less than five minutes at night, when I am half asleep, but through the long day, doing this, that, and the other thing for God and by God and with God, and making Him the motive and the power of my course, and my Companion to heaven. And if we have, in our lives, things over which we cannot make the sign of the cross, the sooner we get rid of them the better; and if there is anything in our daily work, or in our characters, about which we are doubtful, here is a good test: does it seem to check our continual communion with God, as a ligature round the wrist might do the continual flow of the blood, or does it help us to realise His presence? If the former, let us have no more to do with it; if the latter, let us seek to increase it. II. And now let me say a word about the Psalmist's reason for this aspiration.
