George Müller not onlymanaged the orphanage he founded, but also spoke—in his own church and other churches, and later in life in the course of multiple world tours. He is noted for the simplicity of his sermons and for his practical nature of his discourses.
That which I now considered the best mode of preparation for the public ministry of the Word, no longer adopted from necessity, on account of want of time, but from deep conviction, and from the experience of God's blessing upon it, both as it regards my own enjoyment, the benefit of the saints, and the conversion of sinners, is as follows:
1. I do not presume to know myself what is best for the hearers, and I therefore ask the Lord in the first place, that He would graciously be pleased to teach me on what subject I shall speak, or what portion of His word I shall expound. Now sometimes it happens, that previous to my asking Him, a subject or passage has been in my mind, on which it has appeared well for me to speak. In that case I ask the Lord, whether I should speak on this subject or passage. If, after prayer, I feel persuaded that I should I fix upon it, yet so, that I would desire to leave myself open to the Lord to change it, if He please. Frequently, however, it occurs, that I have no text or subject in my mind, before I give myself to prayer for the sake of ascertaining the Lord's will concerning it. In this case I wait some time on my knees for an answer, trying to listen to the voice of the Spirit to direct me. If then a passage or subject, whilst I am on my knees, or after I have finished praying for a text, is brought to my mind, I again ask the Lord, and that sometimes repeatedly, especially if, humanly speaking, the subject or text should be a peculiar one, whether it be His will that I should speak on such a subject or passage. If after prayer my mind is peaceful about it, I take this to be the text, but still desire to leave myself open to the Lord for direction, should He please to alter it, or should I have been mistaken. Frequently also, in the third place, it happens, that I not only have no text nor subject on my mind previous to my praying for guidance in this matter, but also I do not obtain one after once, or twice, or more times praying about it. I used formerly at times to be much perplexed, when this was the case, but for more than forty-five years it has pleased the Lord, in general at least, to keep me in peace about it. What I do is, to go on with my regular reading of the Scriptures, where I left off the last time, praying (whilst I read) for a text, now and then also laying aside my bible for prayer, till I get one. Thus it has happened, that I have had to read five, ten; yea twenty chapters, before it has pleased the Lord to give me a text: yea, many times I have even had to go to the place of meeting without one, and obtained it perhaps only a few minutes before I was going to speak; but I have never lacked the Lord's assistance at the time of preaching, provided I had earnestly sought it in private. The preacher cannot know the particular state of the various individuals who compose the congregation, nor what they require, but the Lord knows it; and if the preacher renounces his own wisdom, he will be assisted by the Lord; but if he will choose in his own wisdom, then let him not be surprised if he should see little benefit result from his labours.
Before I leave this part of the subject, I would just observe one temptation concerning the choice of a text. We may see a subject to be so very full, that it may strike us it would do for some other occasion. For instance, sometimes a text, brought to one's mind for a week-evening meeting, may appear more suitable for the Lord's day, because then there would be a greater number of hearers present. Now, in the first place, we do not know whether the Lord ever will allow us to preach on another Lord's day; and, in the second place, we know not whether that very subject may not be especially suitable for some or many individuals present just that week-evening. Thus I was once tempted, after I had been a short time at Teignmouth, to reserve a subject, which had been just opened to me, for the next Lord's day. But being able, by the grace of God, to overcome the temptation by the above reasons, and preaching about it at once, it pleased the Lord to bless it to the conversion of a sinner, and that too an individual who meant to come but that once more to the chapel, and to whose case the subject was most remarkably suited.
2. Now when the text has been obtained in the above way, whether it be one or two or more verses, or a whole chapter or more, I ask the Lord that He would graciously be pleased to teach me by His Holy Spirit, whilst meditating over it. Within the last fifty years, I have found it the most profitable plan to meditate with my pen in my hand, writing down the outlines, as the Word is opened to me. This I do, not for the sake of committing them to memory, nor as if I meant to say nothing else, but for the sake of clearness, as being a help to see how far I understand the passage. I also find it useful afterwards to refer to what I have thus written. I very seldom use any other help besides the little I understand of the original of the Scriptures, and some good translations in other languages. My chief help is prayer. I have NEVER in my life begun to study one single part of divine truth, without gaining some light about it, when I have been able really to give myself to prayer and meditation over it. But that I have often found a difficult matter, partly on account of the weakness of the flesh, and partly also on account of bodily infirmities and multiplicity of engagements. This I most firmly believe, that no one ought to expect to see much good resulting from his labours in word and doctrine, if he is not much given to prayer and meditation.
3. Having prayed and meditated on the subject or text, I desire to leave myself entirely in the hands of the Lord. I ask Him to bring to my mind what I have seen in my room, concerning the subject I am going to speak on, which He generally most kindly does, and often teaches me much additionally, whilst I am preaching.
In connection with the above, I must, however, state, that it appears to me there is a preparation for the public ministry of the Word, which is even more excellent than the one spoken of. It is this: to live in such constant and real communion with the Lord, and to be so habitually and frequently in meditation over the truth, that without the above effort, so to speak, we have obtained food for others, and know the mind of the Lord as to the subject or the portion of the Word on which we should speak. But this I have only in a small measure experienced, though I desire to be brought into such a state, that habitually "out of my belly may flow rivers of living water."
That which I have found most beneficial in my experience for the last fifty-one years in the public ministry of the Word, is, expounding the Scriptures, and especially the going now and then through a whole gospel or epistle. This may be done in a two-fold way, either by entering minutely into the bearing of every point occurring in the portion, or by giving the general outlines, and thus leading the hearers to see the meaning and connexion of the whole. The benefits which I have seen resulting from expounding the Scriptures are these: 1. The hearers are thus, with God's blessing, led to the Scriptures. They find, as it were, a practical use of them in the public meetings. This induces them to bring their bibles, and I have observed that those who at first did not bring them, have afterwards been induced to do so: so that in a short time few, of the believers at least, were in the habit of coming without them. This is no small matter; for every thing, which in our day will lead believers to value the Scriptures, is of importance. 2. The expounding of the Scriptures is in general more beneficial to the hearers than if, on a single verse, or half a verse, or two or three words of a verse some remarks are made, so that the portion of Scripture is scarcely anything but a motto for the subject; for few have grace to meditate much over the Word, and thus exposition may not merely be the means of opening up to them the Scriptures, but may also create in them a desire to meditate for themselves. 3. The expounding of the Scriptures leaves to the hearers a connecting link, so that the reading over again the portion of the Word, which has been expounded, brings to their remembrance what has been said; and thus, with God's blessing, leaves a more lasting impression on their minds. This is particularly of importance as it regards the illiterate, who sometimes have neither much strength of memory nor capacity of comprehension. 4. The expounding of large portions of the Word, as the whole of a gospel or an epistle, besides leading the hearer to see the connexion of the whole, has also this particular benefit for the teacher, that it leads him, with God's blessing, to the consideration of portions of the Word, which otherwise he might not have considered, and keeps him from speaking too much on favourite subjects, and leaning too much to particular parts of truth, which tendency must surely sooner or later injure both himself and his hearers.- Expounding the word of God brings little honour to the preacher from the unenlightened or careless hearer, but it tends much to the benefit of the hearers in general.
Simplicity in expression, whilst the truth is set forth, is, in connexion with what has been said, of the utmost importance. It should be the aim of the teacher to speak so, that children, servants, and people who cannot read, may be able to understand him, so far as the natural mind can comprehend the things of God. It ought also to be remembered, that there is, perhaps, not a single congregation in which there are not persons of the above classes present, and that if they can understand, the well-educated or literary persons will understand likewise; but the reverse does not hold good. It ought further to be remembered that the expounder of the truth of God speaks for God, for eternity, and that it is not in the least likely that he will benefit the hearers, except he uses plainness of speech, which nevertheless needs not to be vulgar or rude. It should also be considered, that if the preacher strive to speak according to the rules of this world, he may please many, Particularly those who have a literary taste; but, in the same proportion, he is less likely to become an instrument in the hands of God for the conversion of sinners, or for the building up of the saints. For neither eloquence nor depth of thought make the truly great preacher, but such a life of prayer and meditation and spirituality, as may render him a vessel meet for the Master's use, and fit to be employed both in the conversion of sinners and in the edification of the saints.—George Müller, Narratives
