“As it is recorded that David, in the heat of battle, waxed faint, (2 Samuel 21:15) so may it be written of all the servants of the Lord. Fits of depression come over the most of us.

Usually cheerful as we may be, we must at intervals be cast down. The strong are not always vigorous, the wise not always ready, the brave not always courageous, and the joyous not always happy.

There may be here and there men of iron, to whom wear and tear work no perceptible detriment, but surely the rust frets even these; and as for ordinary men, the Lord knows, and makes them to know, that they are but dust.

Knowing by most painful experience what deep depression of spirit means, being visited therewith at seasons by no means few or far between, I thought it might be consolatory to some of my brethren if I gave my thoughts thereon, that younger men might not fancy that some strange thing had happened to them when they became for a season possessed by melancholy; and that sadder men might know that one upon whom the sun has shone right joyously did not always walk in the light.

Our work, when earnestly undertaken, lays us open to attacks in the direction of depression. Who can bear the weight of souls without sometimes sinking to the dust?

Passionate longings after men’s conversion, if not fully satisfied (and when are they?), consume the soul with anxiety and disappointment. To see the hopeful turn aside, the godly grow cold, professors abusing their privileges, and sinners waxing more bold in sin—are not these sights enough to crush us to the earth?

The kingdom comes not as we would, the reverend name is not hallowed as we desire, and for this we must weep. How can we be otherwise than sorrowful, while men believe not our report, and the divine arm is not revealed?

All mental work tends to weary and to depress, for much study is a weariness of the flesh; but ours is more than mental work—it is heart work, the labour of our inmost soul.

How often, on Lord’s-Day evenings, do we feel as if life were completely washed out of us! After pouring out our souls over our congregations, we feel like empty earthen pitchers which a child might break.

Probably, if we were more like Paul, and watched for souls at a nobler rate, we should know more of what it is to be eaten up by the zeal of the Lord’s house. It is our duty and our privilege to exhaust our lives for Jesus.

We are not to be living specimens of men in fine preservation, but living sacrifices, whose lot is to be consumed; we are to spend and to be spent, not to lay ourselves up in lavender, and nurse our flesh.

Such soul-travail as that of a faithful minister will bring on occasional seasons of exhaustion, when heart and flesh will fail. Moses’ hands grew heavy in intercession, and Paul cried out, “Who is sufficient for these things?”

Even John the Baptist is thought to have had his fainting fits, and the apostles were once amazed, and were sore afraid.

There can be little doubt that sedentary habits have a tendency to create despondency in some constitutions. To sit long in one posture, poring over a book, or driving a quill, is in itself a taxing of nature.

But add to this a badly-ventilated chamber, a body which has long been without muscular exercise, and a heart burdened with many cares, and we have all the elements for preparing a seething cauldron of despair, especially in the dim months of fog.

Let a man be naturally as blithe as a bird, he will hardly be able to bear up year after year against such a suicidal process; he will make his study a prison and his books the wardens of a jail, while nature lies outside his window calling him to health and beckoning him to joy.

He who forgets the humming of the bees among the heather, the cooing of the wood-pigeons in the forest, the song of birds in the woods, the rippling of rills among the rushes, and the sighing of the wind among the pines, needs not wonder if his heart forgets to sing and his soul grows heavy.

A day’s breathing of fresh air upon the hills, or a few hours’ ramble in the beech woods’ umbrageous calm, would sweep the cobwebs out of the brain of scores of our toiling ministers who are now but half alive.

A mouthful of sea air, or a stiff walk in the wind’s face, would not give grace to the soul, but it would yield oxygen to the body, which is next best.

The ferns and the rabbits, the streams and the trouts, the fir trees and the squirrels, the primroses and the violets, the farm-yard, the new-mown hay, and the fragrant hops—these are the best medicine for hypochondriacs, the surest tonics for the declining, the best refreshments for the weary.

For lack of opportunity, or inclination, these great remedies are neglected, and the student becomes a self-immolated victim. In the midst of a long stretch of unbroken labour, the same affliction may be looked for.

The bow cannot be always bent without fear of breaking. Repose is as needful to the mind as sleep to the body. Our Sabbaths are our days of toil, and if we do not rest upon some other day we shall break down.

Even the earth must lie fallow and have her Sabbaths, and so must we. Hence the wisdom and compassion of our Lord, when he said to his disciples, “Let us go into the desert and rest awhile.”

What! when the people are fainting? When the multitudes are like sheep upon the mountains without a shepherd? Does Jesus talk of rest?

When Scribes and Pharisees, like grievous wolves, are rending the flock, does he take his followers on an excursion into a quiet resting place?

Does some red-hot zealot denounce such atrocious forgetfulness of present and pressing demands? Let him rave in his folly. The Master knows better than to exhaust his servants and quench the light of Israel.

Rest time is not waste time. It is economy to gather fresh strength. Look at the mower in the summer’s day, with so much to cut down ere the sun sets.

He pauses in his labour— is he a sluggard? He looks for his stone, and begins to draw it up and down his scythe, with “rink-a-tink—rink-a-tink—rink-a-tink.”

Is that idle music— is he wasting precious moments? How much he might have mown while he has been ringing out those notes on his scythe!

But he is sharpening his tool, and he will do far more when once again he gives his strength to those long sweeps which lay the grass prostrate in rows before him.

Even thus a little pause prepares the mind for greater service in the good cause. Fishermen must mend their nets, and we must every now and then repair our mental waste and set our machinery in order for future service.

To tug the oar from day to day, like a galley-slave who knows no holidays, suits not mortal men. Mill-streams go on and on for ever, but we must have our pauses and our intervals.

Who can help being out of breath when the race is continued without intermission?

Even beasts of burden must be turned out to grass occasionally; the very sea pauses at ebb and flood; earth keeps the Sabbath of the wintry months; and man, even when exalted to be God’s ambassador, must rest or faint; must trim his lamp or let it burn low; must recruit his vigour or grow prematurely old.

It is wisdom to take occasional furlough. In the long run, we shall do more by sometimes doing less.

On, on, on for ever, without recreation, may suit spirits emancipated from this “heavy clay,” but while we are in this tabernacle, we must every now and then cry halt, and serve the Lord by holy inaction and consecrated leisure.

Let no tender conscience doubt the lawfulness of going out of harness for awhile, but learn from the experience of others the necessity and duty of taking timely rest.”
