I was reminded of these insights from that great English pastor, Charles Spurgeon in his wonderful book Lectures to My Students
To often the “burden” of ministry is relayed in low pay, long hours, unappreciative people, etc. The reality is perhaps far more personal for many and the occasional reality for all. Spurgeon described is succinctly as the Pastor and His Fainting Fits.
(For a more modern treatment of this subject see Dangerous Calling: Confronting the Unique Challenges of Pastoral Ministry by Paul David Tripp.)
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? … 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?
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.
Our position in the church will also conduce to this. A minister fully equipped for his work, will usually be a spirit by himself, above, beyond, and apart from others. The most loving of his people cannot enter into his peculiar thoughts, cares, and temptations.
The lesson of wisdom is, be not dismayed by soul-trouble. Count it no strange thing, but a part of ordinary ministerial experience. Should the power of depression be more than ordinary, think not that all is over with your usefulness. Cast not away your confidence, for it hath great recompense of reward. Even if the enemy’s foot be on your neck, expect to rise and overthrow him. Cast the burden of the present, along with the sin of the past and the fear of the future, upon the Lord, who forsaketh not his saints. Live by the day—ay, by the hour. Put no trust in frames and feelings. Care more for a grain of faith than a ton of excitement. Trust in God alone, and lean not on the reeds of human help. Be not surprised when friends fail you: it is a failing world. Never count upon immutability in man: inconstancy you may reckon upon without fear of disappointment. The disciples of Jesus forsook him; be not amazed if your adherents wander away to other teachers: as they were not your all when with you, all is not gone from you with their departure. Serve God with all your might while the candle is burning, and then when it goes out for a season, you will have the less to regret. Be content to be nothing, for that is what you are. When your own emptiness is painfully forced upon your consciousness, chide yourself that you ever dreamed of being full, except in the Lord. Set small store by present rewards; be grateful for earnests by the way, but look for the recompensing joy hereafter. Continue, with double earnestness to serve your Lord when no visible result is before you. Any simpleton can follow the narrow path in the light: faith’s rare wisdom enables us to march on in the dark with infallible accuracy, since she places her hand in that of her Great Guide. Between this and heaven there may be rougher weather yet, but it is all provided for by our covenant Head. In nothing let us be turned aside from the path which the divine call has urged us to pursue. Come fair or come foul, the pulpit is our watch-tower, and the ministry our warfare; be it ours, when we cannot see the face of our God, to trust under the shadow of his wings..
