There is no epistle in which the apostle places his apostleship on more positive and formal ground than in this; for at Rome he had no claim in virtue of his labours. He had never seen the Romans. He was none the less their apostle; for he was that of the Gentiles. He was a debtor to the Gentiles. He writes to them because he had received a mission from the Lord Himself towards all the Gentiles. They were in his allotted sphere of service as being Gentiles. It was his office to present them as an offering sanctified by the Holy Ghost (chap. 15:16). This was his commission. God was mighty in Peter towards the Jews; the mission of Paul was to the Gentiles. It was to him this mission was entrusted. The twelve moreover acknowledged it. If God has ordained that Paul should accomplish his mission in direct connection with heaven and outside the secular influence of the capital, and if Rome was to be a persecutor of the gospel, that city was not the less Gentile on this account. It belonged to Paul with reference to the gospel. According to the Holy Ghost Peter addresses the Jews in the exercise of his apostleship; Paul, the Gentiles.
This was the administrative order according to God; let us now come to the substance of his position. Paul was the servant of Christ-that was his character, his life. But others were, more or less, that. He was more than that. He was an apostle by the call of the Lord, a "called apostle"; and not only that, and laborious as occasion presented itself, he was nothing but that in life here below. He was set apart for the glad tidings of God.
These two last characters are very definitely warranted by the revelation of the Lord to Paul on the way to Damascus-his call, and his mission to the Gentiles on that occasion; and by setting apart by the Holy Ghost at Antioch, when he went forth to fulfil his mission.
He calls the gospel to which he was set apart, the gospel or glad tidings "of God": the Holy Ghost presents it in its source. It is not that which man ought to be for God, nor yet the means merely by which man can approach Him on His throne. It is the thoughts of God, and His acts, we may add, towards man-His thoughts in goodness, the revelation of Him in Christ His Son. He approaches man according to that which He is and that which He wills in grace. God comes to him; it is the gospel of God. This is the true aspect: the gospel is never rightly understood until it is to us the gospel of God, the activity and revelation of His nature, and of His will in grace towards man.
Having pointed out the source, the Author of the gospel, the One whom it thus reveals in His grace, the apostle presents the connection between this gospel and the dealings of God which historically preceded it-its promulgation here below, and at the same time its own proper object; that is to say, its subject properly so called, and the place held with regard to it by that which preceded it (the order of things which those to whom they belonged sought to maintain as a substantive and independent system by rejecting the gospel). He here introduces that which preceded, not as a subject of controversy, but in its true character, to enforce the testimony of the gospel (anticipating objections, which are thus solved beforehand).
To the Gentile it was the revelation of the truth, and of God, in grace; to the Jew it was indeed that, while also putting everything that regarded him in its right place. The connection of the Old Testament with the gospel is this: the gospel of God had been announced beforehand by His prophets in holy writings. Observe here, that in these holy scriptures the gospel of God was not come, nor was it then addressed to men: but promised or announced beforehand, as to be sent. The assembly was not even announced: the gospel was announced, but as being yet to come.
Moreover, the subject of this gospel is, first of all, the Son of God. He has accomplished a work: but it is Himself who is the true subject of the gospel. Now He is presented in a twofold aspect: 1st, the object of the promises, Son of David according to the flesh; 2nd, the Son of God in power, who, in the midst of sin, walked by the Spirit in divine and absolute holiness (resurrection being the illustrious and victorious proof of who He was, walking in this character). That is to say, resurrection is a public manifestation of that power by which He walked in absolute holiness during His life-a manifestation that He is the Son of God in power. He is clearly shewn forth as Son of God in power by this means Here it was no question of promise, but of power, of Him who could enter into conflict with the death in which man lay, and overcome it completely; and that, in connection with the holiness which bore testimony during His life to the power of that Spirit by which He walked, and in which He guarded Himself from being touched by sin. It was in the same power by which He was holy in life absolutely that He was raised from the dead.
In the ways of God on the earth He was the object and the fulfilment of the promises. With regard to the condition of man under sin and death, He was completely conqueror of all that stood in His way, whether living or in resurrection. It was the Son of God who was there, made known by resurrection according to the power that was in Him, a power that displayed itself according to the Spirit by the holiness in which He lived.  What marvellous grace to see the whole power of evil-that dreadful door of death which closed upon the sinful life of man, leaving him to the inevitable judgment that he deserved-broken, destroyed, by Him, who was willing to enter into the gloomy chamber it shut in, and take upon Himself all the weakness of man in death, and thus completely and absolutely deliver him whose penalty He had borne in submitting to death! This victory over death, this deliverance of man from its dominion, by the power of the Son of God become man, when He had undergone it, and that as a sacrifice for sin, is the only ground of hope for mortal and sinful man. It sets aside all that sin and death have to say. It destroys, for him who has a portion in Christ, the seal of judgment upon sin, which is in death; and a new man, a new life, begins for him who had been held under it, outside the whole scene, the whole effect of his former misery-a life founded on all the value of that which the Son of God had there accomplished.
In fine, we have, as the subject of the gospel, the Son of God, made of the seed of David after the flesh; and, in the bosom of humanity and of death, declared to be the Son of God in power by resurrection,  Jesus Christ our Lord. The gospel was the gospel of God Himself; but it is by Jesus Christ the Lord that the apostle received his mission. He was the head of the work, and sent forth the labourers into the harvest which they were to reap in the world. The object of his mission, and its extent, was the obedience of faith (not obedience to the law) among an nations, establishing the authority and the value of the name of Christ. It was this name which should prevail and be acknowledged.
The apostle's mission was not only his service; the being trusted with it was at the same time the personal grace and favour of Him whose testimony he bore. I am not speaking of salvation, although in Paul's case the two things were identified-a fact that gave a remarkable colour and energy to his mission; but there was grace and favour in the commission itself, and it is important to remember it. It gives character to the mission and to its execution. An angel performs a providential mission; a Moses details a law in the spirit of the law; a Jonah, a John the Baptist, preaches repentance, withdraws from the grace that appeared to falsify his threatenings against the wicked Gentiles, or in the wilderness lays the axe to the root of the unfruitful trees in God's garden. But by Jesus, Paul, the bearer of the glad tidings of God, receives grace and apostleship. He carries, by grace and as grace, the message of grace to men wherever they may be, the grace which comes in all the largeness of the rights of God over men, and in Himself as sovereign, and in which He exercises His rights. Among these Gentiles, the believing Romans also were the called of Jesus Christ.
Paul therefore addresses all the believers in that great city. They were beloved of God, and saints by calling.  He wishes them (as in all his epistles) grace and peace from God the Father and from the Lord Jesus Christ, on whose part he delivered his message. The perfect grace of God by Christ, the perfect peace of man, and that with God; it was this which he brought in the gospel and in his heart. These are the true conditions of God's relationship with man, and that of man with God, by the gospel-the ground on which Christianity places man. When an individual is addressed, another consideration comes in, namely, that of his own weaknesses and infirmities: therefore "mercy" is added to the wish of the sacred writers in the case of individuals. (See the Epistles to Timothy and Titus, and the Second Epistle of John.)  If the love of God is in the heart, if He has His place there, it is before God that one is occupied with the objects of grace; and then, the work of God in them, the grace that has been displayed is the first thing that comes into the mind, whether in love or in thankfulness. The faith of the Romans ascends in thanksgivings from the heart of the apostle, whom the report of it had reached.
He then expresses his desire to see them, a desire that often occupied his mind. Here he brings out his apostolic relationship towards them, with all the tenderness and all the delicacy that belong to the grace and the love which had formed this relationship and which constituted its strength. He is apostle by right to all the Gentiles, even although he may not have seen them; but in heart he is their servant; and with the most true and ardent brotherly love, flowing from the grace that had made him apostle, he desires to see them, that he might impart to them some spiritual gift, which his apostleship put him in a position to communicate. What he had in his heart in this was, that he might enjoy the faith which was common to him and to them-faith strengthened by these gifts-for their mutual comfort. Often he had purposed coming, that he might have some fruit in this part also of the field which God had committed to him; but he had been hindered until now.
He then declares himself a debtor to all the Gentiles, and ready, as far as in him lay, to preach the gospel to those of Rome also. The way in which the apostle claims the whole field of the Gentiles as his own, and in which he was prevented by God from going to Rome until he arrived there at the end of his career (and then only as a prisoner), is worthy of all attention.
However it might be, he was ready, and that because of the value of the gospel-a point which leads him to state both the value and the character of this gospel. For, he says, he was not ashamed of it. It was the power of God to salvation. Observe here the way in which the apostle presents everything as coming from God. It is the gospel of God, the power of God to salvation, the righteousness of God, and even the wrath of God, and that from heaven-a different thing from earthly chastisement. This is the key to everything. The apostle lays stress upon it, putting it forward from the commencement of the epistle; for man ever inclines to have confidence in himself, to boast of himself, to seek for some merit-some righteousness, in himself, to Judaise, to be occupied with himself, as though he could do something. It was the apostle's joy to put his God forward.
Thus, in the gospel, God intervened, accomplishing a salvation which was entirely His own work-a salvation of which He was the source and power, and which He Himself had wrought. Man came into it by faith: it was the believer who shared it, but to have part in it by faith was exactly the way to share it without adding anything whatsoever to it, and to leave it wholly the salvation of God. God be praised that it is so, whether for righteousness or for power, or for the whole result; for thus it is perfect, divine. God has come in, in His almighty power and in His love, to deliver the wretched, according to His own might. The gospel is the expression of this: one believes it and one shares it.
But there is an especial reason why it is the power of God in salvation. Man had departed from God by sin. Righteousness alone could bring him back into the presence of God, and make him such that he could be there in peace. A sinner, he had no righteousness, but quite the contrary; and if man were to come before God as a sinner, judgment necessarily awaits him: righteousness would be displayed in this way. But, in the gospel, God reveals a positive righteousness on His part. If man has none, God has a righteousness which belongs to Him, which is His own, perfect like Himself, according to His own heart. Such a righteousness as this is revealed in the gospel. Human righteousness there was none: a righteousness of God is revealed. It is all-perfect in itself, divine and complete. To be revealed, it must be so. The gospel proclaims it to us.
The principle on which it is announced is faith, because it exists, and it is divine. If man wrought at it, or performed a part of it, or if his heart had any share in carrying it out, it would not be the righteousness of God; but it is entirely and absolutely His. We believe in the gospel that reveals it. But if it is the believer who participates in it, every one who has faith has part in it. This righteousness is on the principle of faith. It is revealed, and consequently to faith, wherever that faith exists.
This is the force of the expression which is translated "from faith to faith"-on the principle of faith unto faith. Now the importance of this principle is evident here. It admits every believing Gentile on the same footing as the Jew, who has no other right of entrance than he. They both have faith: the gospel recognises no other means of participating in it. The righteousness is that of God; the Jew is nothing more in it than the Gentile. As it is written, "The just shall live by faith." The scriptures of the Jews testified to the truth of the apostle's principle.
This is what the gospel announced on God's part to man. The primary subject was the Person of Christ, son of David according to flesh (accomplishment of promise); and the Son of God with power according to the Spirit of holiness. But the righteousness of God (not of man) was revealed in it. This is the grand theme of all that follows. The apostle had indeed reason not to be ashamed of it, despised as it was by men.
But this doctrine was confirmed by another consideration, and was based on the great truth contained in it. God, in presenting Himself, could not look at things according to the partial communications adapted to the ignorance of men, and to the temporary dispensations by which He governed them. Wrath was not merely His intervention in government, as by the Assyrian or Babylonish captivity. It was "wrath from heaven." The essential opposition of His nature to evil, and penal rejection of it wherever it was found, was manifested. Now God manifested Himself in the gospel. Thus divine wrath does not break forth indeed (for grace proclaimed the righteousness of God in salvation for sinners who should believe) but it is revealed (not exactly in the gospel-that is the revelation of righteousness; but it is revealed) from heaven against ungodliness-all that does not respect the presence of God-against all that does not comport with the presence of God, and against all unrighteousness or iniquity in those who possessed the truth but still dishonoured God; that is to say, against all men, Gentile or otherwise, and particularly the Jews who had the knowledge of God according to the law; and, again (for the principle is universal, and flows from that which God is, when He reveals Himself), against every one who professes Christianity, when he walks in the evil that God hates.
This wrath, divine wrath, according to God's nature as in heaven, against man as a sinner, made God's righteousness necessary. Man was now to meet God fully revealed as He is. This shewed him wholly a sinner, but paved the way in grace for a far more excellent place and standing-one based on the righteousness of God. The gospel reveals the righteousness: its opportuneness and necessity are demonstrated by the state of sin in which all men are, and by occasion of which wrath was revealed from heaven. Man was not merely to be governed by God, and find governmental wrath, but to appear before God. How could we stand there? The answer is the revelation of God's righteousness by the gospel. Hence, too, even in speaking of resurrection Christ is declared to be the Son of God according to the Spirit of holiness. God has to be met such as He is. The revelation of God Himself in His holy nature went necessarily farther than mere Jews. It was against the thing sin, wherever it was, wherever it met sin, to make good what God is. It is a glorious truth; and how blessed that thus divine righteousness in sovereign grace should be revealed! And, God being love, we can say that it could not be otherwise; but how glorious to have God thus revealed!
The thesis of the epistle then is in verse 17, that which proved its need in verse 18. From verse 19 to the end of verse 20 in chapter 3, the condition of men, Jews and Gentiles, to whom this truth applies, is given in detail, in order to shew in what way this wrath was deserved, and all were shut up in sin (v. 19 and 21 of this chapter giving the leading principles of the evil as regards the Gentiles). From verse 21 to 31 of chapter 3, the answer in grace by the righteousness of God, through the blood of Christ, is briefly but powerfully declared. For we first get the answer by Christ's blood to the old state, and then the introduction, by death and life through Christ, into the new.
The apostle begins with the Gentiles-"all ungodliness" of men. I say the Gentiles (it is evident that if a Jew falls into it, this guilt attaches to him; but the condition described, as far as chapter 2:17, is that of Gentiles); afterwards that of the Jews, to chapter 3:20.
Chapter 1:18 is the thesis of the whole argument from verse 19 to chapter 3:20, this part of the epistle shewing the ground of that wrath.
The Gentiles are without excuse on two accounts. First, that which may be known of God has been manifested by creation-His power and His Godhead. This proof has existed since the creation of the world. Secondly, that, having the knowledge of God as Noah had it, they had not glorified Him as God, but in the vanity of their imaginations, reasoning upon their own thoughts on this subject and the ideas it produced in their own minds, they became fools while professing themselves to be wise, and fell into idolatry, and that of the grossest kind. Now God has judged this. If they would not retain a just thought of the glory of God, they should not even retain a just idea of the natural honour of man. They should dishonour themselves as they had dishonoured God. It is the exact description, in a few strong and energetic words, of the whole pagan mythology. They had not discernment, moral taste, to retain God in their knowledge: God gave them up to a spirit void of discernment, to boast themselves in depraved tastes, in things unbecoming nature itself. The natural conscience knew that God judged such things to be worthy of death according to the just exigencies of His nature. Nevertheless they not only did them, but they took pleasure in those who did them, when their own lusts did not carry them away. And this left no excuse for those who judged the evil (and there were such), for they committed it while judging it. Man then by judging condemned himself doubly: for by judging he shewed that he knew it to be evil, and yet he did it. But the judgment of God is according to truth against those who commit such things: they who acquired credit by judging them should not escape it.
