The self-same principle applies to the so-called sermon on the mount, on which I am about to say a few words. It is quite a misapprehension to suppose that Matthew 5-7 was given all in a single, unbroken discourse.
For the wisest purposes, I have no doubt, the Spirit of God has arranged and conveyed it to us as one whole, without notice of the interruptions, occasions, and so forth; but it is an unwarrantable conclusion for any to draw, that our Lord Jesus delivered it simply and solely as it stands in Matthew’s Gospel. What proves the fact is, that in the Gospel of Luke we have certain portions of it clearly pertaining to this very sermon (not merely similar, or the same truth preached at other times, but this identical discourse), with the particular circumstances which drew them out. Take the prayer, for instance, that was here set before the disciples (Matt. 6). As to this, we know from Luke 11 there was a request preferred by the disciples which led to it. As to other instruction, there were facts or questions, found in Luke, which drew out the remarks of the Lord, common to him and Matthew, if not Mark.
If it be certain that the Holy Spirit has been pleased to give us in Matthew this discourse and others as a whole, leaving out the originating circumstances found elsewhere, it is a fair and interesting inquiry why such a method of grouping with such omissions is adopted. The answer I conceive to be this,—that the Spirit in Matthew loves to present Christ as the One like unto Moses, whom they were to hear. He presents Jesus not merely as a legislating prophet-king like Moses, but greater by far; for it is never forgotten that the Nazarene was the Lord God. Therefore it is that, in this discourse on the mountain, we have throughout the tone of One who was consciously God with men. If Jehovah called Moses up to the top of one mount, He who then spake the ten words sat now upon another mount, and taught His disciples the character of the kingdom of heaven, and its principles introduced as a whole, just answering to what we have seen of the facts and effects of His ministry, entirely passing by all intervals or connecting circumstances. As we had His miracles all put together as I may say, in the gross, so with His discourses. We have thus in either case the same principle. The substantial truth is given to us without noticing the immediate occasion in particular facts, appeals, and so forth. What was uttered by the Lord, according to Matthew, is thus presented as a whole. The effect, therefore, is, that it is much more solemn, because unbroken, carrying its own majesty along with it. The Spirit of God imprints on it purposely this character here, as I have no doubt there was an intention that it should be so reproduced for the instruction of His own people.
The Lord, in short, was here accomplishing one of the parts of His mission according to Isaiah 53, where the work of Christ is twofold. It is not, as the authorized version has it, “By His knowledge shall my righteous servant justify many” (Isa. 53:1111He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities. (Isaiah 53:11)); for it is unquestionable that justification is not by His knowledge. Justification is by faith of Christ, we know; and as far as the efficacious work on which it depends is concerned, it is clearly in virtue of what Christ has suffered for sin and sins before God. But I apprehend that the real force of the passage is, “By His knowledge shall my righteous servant instruct many in righteousness.” It is not “justify” in the ordinary forensic sense of the word, but rather instructing in righteousness, as the context here requires, and as the usage of the word elsewhere, as in Daniel 12, leaves open. This seems to be what is meant of our Lord here.
In the teaching on the mount He was, in fact, instructing the disciples in righteousness: hence, too, one reason why we have not a word about redemption. There is not the slightest reference to His suffering on the cross; no intimation of His blood, death, or resurrection; He is instructing, though not merely in righteousness. To the heirs of the kingdom the Lord is unfolding the principles of that kingdom,—most blessed and rich instruction, but instruction in righteousness. No doubt there is also the declaration of the Father’s name, as far as could be then; but, still, the form taken is that of “instructing in righteousness.” Let me add, as to the passage of Isaiah 53, that the remainder of the verse also accords with this: not “for,” but, “and He shall bear their iniquities.” Such is the true force of it. The one was in His life, when He taught His own; the other was in His death, when He bore the iniquities of many.
Into the details of the discourse on the mount I cannot enter particularly now, but would just say a few words before I conclude tonight. In its preface we have a method often adopted by the Spirit of God, and not unworthy of our study. There is no child of God that cannot glean blessing from it, even through a scanty glance; but when we look into it a little more closely, the instruction deepens immensely. First of all He pronounces certain classes blessed. These blessednesses divide into two classes. The earlier character of blessedness savors particularly of righteousness, the later of mercy, which are the two great topics of the Psalms. These are both taken up here: “Blessed are the poor in spirit: for theirs is the kingdom of heaven. Blessed are they that mourn: for they shall be comforted. Blessed are the meek: for they shall inherit the earth. Blessed are they which do hunger and thirst after righteousness: for they shall be filled.” In the fourth case righteousness comes in expressly, and closes that part of the subject; but it is plain enough that all these four classes consist in substance of such as the Lord pronounces blessed, because they are righteous in one form or another. The next four are founded upon mercy. Hence we read as the very first, “Blessed are the merciful: for they shall obtain mercy. Blessed are the pure in heart: for they shall see God. Blessed are the peacemakers: for they shall be called the children of God.” Of course, it would be impossible to attempt more than a sketch at this time. Here, then, occurs the number usual in all these systematic partitions of Scripture; there is the customary and complete seven of Scripture. The two supplementary blessednesses at the end rather confirm the case, though at first sight they might appear to offer an exception. But it is not so really. The exception proves the rule convincingly; for in verse 10 you have, “Blessed are they which are persecuted for righteousness’ sake;” which answers to the first four. Then, in verses 11 and 12, you have, “Blessed are ... ye for my sake;” which answers to the higher mercy of the last three. “Blessed are ye, [there is thus a change. It is made a direct personal address] when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake” (vs. 11). Thus it is the very consummation of suffering in grace, because it is for Christ’s sake.
Hence the twofold persecutions (vss.10-12) bring in the double character we find in the epistles—suffering for righteousness’ sake, and suffering for Christ’s sake. These are two perfectly distinct things; because, where it is a question of righteousness, it is simply a person brought to a point. If I do not stand and suffer here, my conscience will be defiled; but this is in no way suffering for Christ’s sake. In short, conscience enters where righteousness is the question; but suffering for Christ’s sake is not a question of plain sin, but of His grace and its claims on my heart. Desire for His truth, desire for His glory, carries me out into a certain path that exposes me to suffering. I might merely do my duty in the place in which I am put; but grace is never satisfied with the bare performance of one’s duty. Fully is it admitted that there is nothing like grace to meet duty; and doing one’s duty is a good thing for a Christian. But God forbid that we should be merely shut up to duty, and not be free for the flowing over of grace which carries out the heart along with it. In the one case, the believer stops dead short: if he did not stand, there would be sin. In the other case, there would be a lack of testimony for Christ, and grace makes one rejoice to be counted worthy of suffering for His name: but righteousness is not in question.
Such, then, are the two distinct classes or groups of blessedness. First, there are the blessednesses of righteousness, to which the persecution for righteousness’ sake pertains; next, the blessednesses of mercy or grace.
Christ instructs in righteousness according to prophecy, but He does not confine Himself to righteousness. This never could be consistent with the glory of the person who was there. Accordingly, therefore, while there is the doctrine of righteousness, there is the introduction of what is above it and mightier than it, with the corresponding blessedness of being persecuted for Christ’s sake. All here is grace, and indicates manifest progress.
The same thing is true of what follows: “Ye are the salt of the earth”—it is that which keeps pure what is pure. Salt will not communicate purity to what is impure, but it is used as the preservative power according to righteousness. But light is another thing. Hence we hear, in the 14th verse, “Ye are the light of the world.” Light is not that which simply preserves what is good, but is an active power, which casts its bright shining into what is obscure, and dispels the darkness from before it. Thus it is evident that in this further word of the Lord we have answers to the differences already hinted at.
Much of the deepest interest might be found in the discourse; only this is not the occasion for entering into particulars. We have, as usual, righteousness developed according to Christ, which deals with man’s wickedness under the heads of violence and corruption; next come other new principles of grace infinitely deepening what had been given under law (Matt. 5). Thus, in the former of these, a word detects, as it were, the thirst of blood, as corruption lies in a look or desire. For it is no longer a question of mere acts, but of the soul’s condition. Such is the scope of the fifth chapter.
As in earlier verses 17-18 the law is fully maintained in all its authority, we have later on (verses 21-48) superior principles of grace, and deeper truths, mainly founded upon the revelation of the Father’s name—the Father which is in heaven. Consequently it is not merely the question between man and man, but the Evil One on one side, and God Himself on the other; and God Himself, as a Father, disclosing and proving the selfish condition of fallen man upon the earth.
