And so, dear brethren! though it be the A B C of Christian teaching, suffer this word of exhortation. It is only 'milk for babes,' but it is milk that the babes are very unwilling to take. Learn from this verse before us the solemn duty of rigid control, by the higher self, of the tremulous, emotional lower self which responds so completely to every change of temperature or circumstances in the world without. And remember that there should be a central heat which keeps the temperature substantially the same, whatever be the weather outside. As the wheel-house, and the steering gear, and the rudder of the ship proclaim their purpose of guidance and direction, so eloquently and unmistakably does the make of our inward selves tell us that emotions and moods and tempers are meant to be governed, often to be crushed, always to be moderated, by sovereign will and reason. In the Psalmist's language, 'My soul' has to give account of its tremors and flutterings to 'Me,' the ruling Self, who should be Lord of temperament, and control the fluctuations of feeling.
II. Note that there are two ways of looking at causes of dejection and disquiet.
The whole preceding parts of both the psalms, before this refrain, are an answer to the question which my text puts. 'Why art thou cast down, O my soul?' 'My soul' has been talking two whole psalms, to explain why it is cast down. And after all the eloquent torrent of words to vindicate and explain its reasons for sadness--separation from the sanctuary, bitter remembrances of bright days, which the poet tells us are 'a sorrow's crown of sorrow,' taunts of enemies and the like--after all these have been said over and over again, the Psalmist says to himself: 'Come now, let us hear it all once more. _Why_ art thou cast down? Why art thou disquieted within me? Thou hast been telling the reasons abundantly. Speak them once again, and let us have a look at them.'
There is a court of appeal in each man, which tests and tries his reasons for his moods; and these, which look very sufficient to the flesh, turn out to be very insufficient when investigated and tested by the higher spirit or self. We should 'appeal from Philip drunk to Philip sober.' And if a man will be honest with himself, and tell himself why he is in such a pucker of terror, or why he is in such a rapture of joy, nine times out of ten the attempt to tell the reasons will be the condemnation of the mood which they are supposed to justify. If men would only bring the causes or occasions of the tempers and feelings which they allow to direct them, to the bar of common sense, to say nothing of religious faith, half the furious boilings in their hearts would stop their ebullition. It would be like pouring cold water into a kettle on the fire. It would end its bubbling. Everything has two handles. The aspect of any event depends largely on the beholder's point of view. 'There's nothing either good or bad, but thinking makes it so.' 'Why art thou cast down, O my soul? and why art thou disquieted within me?' The answer is often very hard to give; the question is always very salutary to ask.
III. Note that no reasons for being cast down are so strong as those for elation and calm hope.
'Hope thou in God, for I shall yet praise Him, who is the health of my countenance and my God.' I need not deal here with the fact that the first of the three occurrences of this refrain is, in our Bible, a little different from the other two. That is probably a mistake in the text. In all three cases the words ought to stand the same.
