And what thus brought a cloud over his sky? A little exercise of historical imagination will very sufficiently answer that. A few weeks before, in obedience, as he believed, to a direct divine command, Paul had made a plunge, and ventured upon an altogether new phase of work. He had crossed into Europe, and from the moment that he landed at the harbour of Philippi, up to the time when he took refuge in some quiet little room in Corinth, he had had nothing but trouble and danger and disappointment. The prison at Philippi, the riots that hounded him out of Thessalonica, the stealthy, hurried escape from Beroea, the almost entire failure of his first attempt to preach the Gospel to Greeks in Athens, his loneliness, and the strangeness of his surroundings in the luxurious, wicked, wealthy Greek city of Corinth--all these things weighed on him, and there is no wonder that his spirits went down, and he felt that now he must lie fallow for a time and rest, and pull himself together again.
So here we have, in this great champion of the faith, in this strong runner of the Christian race, in this chief of men, an example of the fluctuation of mood, the variation in the way in which we look at our duties and our obligations and our difficulties, the slackening of the impulse which dominates our lives, that are too familiar to us all. It brings Paul nearer us to feel that he, too, knew these ups and downs. The force that drove this meteor through the darkness varied, as the force that impels us varies to our consciousness. It is the prerogative of God to be immutable; men have their moods and their fluctuations. Kindled lights flicker; the sun burns steadily. An Elijah to-day beards Ahab and Jezebel and all their priests, and to-morrow hides his head in his hands, and says, 'Take me away, I am not better than my fathers.' There will be ups and down in the Christian vigour of our lives, as well as in all other regions, so long as men dwell in this material body and are surrounded by their present circumstances.
Brethren, it is no small part of Christian wisdom and prudence to recognise this fact, both in order that it may prevent us from becoming unduly doubtful of ourselves when the ebb tide sets in on our souls, and also in order that we may lay to heart this other truth, that because these moods and changes of aspect and of vigour _will_ come to us, therefore the law of life must be effort, and the duty of every Christian man be to minimise, in so far as possible, the fluctuations which, in some degree, are inevitable. No human hand has ever drawn an absolutely straight line. That is the ideal of the mathematician, but all ours are crooked. But we may indefinitely diminish the magnitude of the curves. No two atoms are so close together as that there is no film between them. No human life has ever been an absolutely continuous, unbroken series of equally holy and devoted thoughts and acts, but we may diminish the intervals between kindred states, and may make our lives so far uniform as that to a bystander they shall look like the bright circle, which a brand whirled round in the air makes the impression of, on the eye that beholds. We shall have times of brightness and of less brilliancy, of vigour and of consequent reaction and exhaustion. But Christianity has, for one of its objects, to help us to master our moods, and to bring us nearer and nearer, by continual growth, to the steadfast, immovable attitude of those whose faith is ever the same.
Do not forget the plain lesson which comes from the incident before us--viz., that the wisest thing that a man can do, when he feels that the wheels of his religious being are driving heavily, is to set himself doggedly to the plain, homely work of daily life. Paul did not sit and bemoan himself because he felt this slackening of impulse, but he went away to Aquila, and said, 'Let us set to work and make camel's-hair cloth and tents.' Be thankful for your homely, prosaic, secular, daily task. You do not know from how many sickly fancies it saves you, and how many breaches in the continuity of your Christian feeling it may bridge over. It takes you away from thinking about yourselves, and sometimes you cannot think about anything less profitably. So stick to your work; and if ever you feel, as Paul did, 'cast down,' be sure that the workshop, the office, the desk, the kitchen will prevent you from being 'destroyed,' if you give yourselves to the plain duties which no moods alter, but which can alter a great many moods.
