At the head of them all, in this respect, stands Isaiah. If the book of an ordinary reader of the Bible were examined, it would be found, I imagine, that Isaiah is thumbed far more than any other portion of the prophetical writings; and this is due not only to the divinely evangelical character of his message, but also to the nobly human style of his language.[26] All the resources of poetry and eloquence are at his command. Every realm of nature ministers to his stores of imagery; and his language ranges through every mode of beauty and sublimity, being sometimes like the pealing of silver bells, and sometimes like the crashing of avalanches, and sometimes like the songs of seraphim. He is generally supposed to have been a native of Jerusalem and to have spent his life within its walls. So identified, indeed, is he with it, that he is coming to be called Isaiah of Jerusalem; and a recent expounder of his prophecies says that Jerusalem was more to him than Athens to Demosthenes, Rome to Juvenal, or Florence to Dante. But, at some period of his life, he must have had ample experience also of a country life; because the aspects of the country are mirrored in his pages with incomparable charm.
He lets us see nature, as it existed in his day, both wild in the forest and wilderness, and cultivated around the abodes of men; and he paints for us the figures of the country people themselves and the labours they went forth to. We see in his pages the trees of the wood moved by the wind; the willows by the water-courses; the fresh branches sprouting from the stock of the pollard oak or terebinth. We hear the doves mourning from the depths of the thicket, and see the roe, chased by the hunter, disappearing within its shelter, and even the schoolboy rifling the birds' nests so ruthlessly that "there was none that moved the wing or opened the mouth or peeped." We see the swarms of bees and flies resting on the branches in the summer heat; the ploughshare lying in the furrow; the tow and the distaff; the ox turning its head to be patted by the hand of its owner, and the ass trotting off at feeding-time to its master's crib. The prophet looks with a specially observant and sympathetic eye on the toils of men—the woodman thinning the trees of the forest; the carpenter, with saw and axe, turning to his own uses the sycamore and the cedar; the builder among his bricks and stones; and the farmer, on the exposed height of the threshing-floor, winnowing his corn with the shovel and the fan. As is usual in the Bible, the shepherd is portrayed with special honour, whether he calls out his neighbours to frighten away the lion from his flock or is seen gathering the lambs in his arms and carrying them in his bosom. But most of all does the poet-prophet love to linger in the vineyard, marking accurately all the operations of the vine-dresser and all the stages of the growth of the vines. We see the tearing up of the hillside with the mattock, the accumulation of soil, the gathering out of the stones, the construction of the winepress and the watch-tower. Then we see the roots planted and growing from stage to stage—from that "afore the harvest, when the bud is perfect and the sour grape is ripening in the flower," to that when the vineyard is ringing with the songs of the vintage and the gleaners are picking the last relics from the outermost branches.
At whatever period these pictures of nature were laid up in the memory of Isaiah, they came back to him when he was engaged in the work of a prophet, and supplied the imagery by means of which the Divine truths which he heralded were made impressive and attractive to his countrymen and acceptable to all subsequent generations; for men are so made that they are never so won by the truth as when they see it reflected in a physical image.
These two sides of the prophet's activity nearly correspond to what we should call Thought and Expression. Or, to put it still more broadly, the preacher must be a man who both has something to say and knows how to say it. On these two apparently simple qualifications hang all the science and art of our vocation.
In reality they are not simple. To have the right thing to say is a great commandment, and to know the right way to say it is, though second to it, hardly inferior. But the problem of the ministry is to have both in perfect equipoise—to utter a word which is at the same time both a message from God and a message to men.
It would be possible to be so taken possession of by the message from God as to lose self-control and even reason itself. In Scripture we meet with manifestations of prophecy which are akin to madness. Just as the wind, catching the sail, would, if the ropes were not adjusted to relieve the strain, overturn the boat, so the Wind of God might sweep the mind off its balance, the human personality being overborne by the inrushing inspiration. Thus religion may make a man a fanatic, who has no control over his own spirit, and no wisdom to choose the times at which to speak or the terms in which to address his fellow-men. On the other hand, the opposite excess is still more easy. So much stress may be laid on the form of words, and so much mastery obtained of the art of winning attention, that the necessity of having a Divine message to deliver or of depending on the power of the Spirit of God is forgotten. The windy master of words, whose own spirit is not subdued either by the impression of great thoughts or the sense of a great responsibility, but who can draw the eyes of men on his own performances and earn the incense of applause, has always been too familiar a figure in religion. It is to a man like Isaiah we must look for the absolute balance of both sides. There you have the blowing in all its degrees of the Wind of God, from the gentlest whisper to the force of the tempest, but, at the same time, the most perfect self-control and the adaptation of the word to the tastes and necessities of those to whom it was delivered.
There is a name sometimes applied by the prophets to themselves which admirably expresses the combination and balance of these two aspects of their activity. They call themselves Interpreters. The process of interpretation is a most interesting one, when it is well done. I have heard a speaker address with the greatest fervour a multitude who did not understand a word he was saying; but, as fast as the sentences fell from his lips, another speaker by his side caught them up and, in tones as fervid and with gestures as dramatic as his own, rendered them to the hearers in their own tongue with such effect that the performance made all the impression of an original speech. An interpreter is one who receives a message for people in a language which they do not understand and delivers it to them in their own tongue. Jehovah was incessantly speaking to His people in the vicissitudes of their history, but they did not apprehend His meaning. The prophet, however, understood; he took the Divine message into his own soul, and then he went and communicated it to the people in terms with which they were familiar. An interpreter requires to know at least two languages—that in which the message comes and that in which it has to be delivered. If he knows either imperfectly, his interpretation will be proportionately imperfect. No interpreter of God, perhaps, knows both languages equally well. Some know the Divine language imperfectly, while they know thoroughly the language of men. What they say is interesting, fresh and human; but there is not much of a Divine message in it. Others have got far into the secret of God and know the Divine language well; but they are not sufficiently masters of the language of men. These are saintly men and command reverence by their character, but what they say does not find its way to men's business and bosoms.
I have seen the same truth put in another way. Tholuck, one of the most gifted of modern preachers, has made the remark that a sermon ought to have heaven for its father and the earth for its mother. Why, he asks, do one half of our sermons miss the mark? It is because, while they treat of the circumstances and relationships of life in an interesting way, they do so only in the light which springs from below, not in that which streams from above; they have the earth for their mother, but not heaven for their father. And why do the other half of our sermons fail to touch the heart? It is because, while they display the heavenly things shining at a distance, they do not bring them down to the homes and workshops, the highways and byways of ordinary life; they have heaven for their father, but not the earth for their mother.[27]
Indeed, gentlemen, the definition of the preacher as a Man of the Word covers a very large area of our duty, and an analysis of its contents will furnish a kind of natural history of that which is the most important part of a minister's work from week to week.
