31 What then [is] the superiority of the Jew? or what the profit of circumcision? 2 Much every way: and first, indeed, that to them were entrusted the oracles of God. 3 For what? if some have not believed, shall their unbelief make the faith of God of none effect? 4 Far be the thought: but let God be true, and every man false; according as it is written, So that thou shouldest be justified in thy words, and shouldest overcome when thou art in judgment. 5 But if our unrighteousness commend God's righteousness, what shall we say? Is God unrighteous who inflicts wrath? I speak according to man. 6 Far be the thought: since how shall God judge the world? 7 For if the truth of God, in my lie, has more abounded to his glory, why yet am I also judged as a sinner? 8 and not, according as we are injuriously charged, and according as some affirm that we say, Let us practise evil things, that good ones may come? whose judgment is just.
9 What then? are we better? No, in no wise: for we have before charged both Jews and Greeks with being all under sin: 10 according as it is written, There is not a righteous [man], not even one; 11 there is not the [man] that understands, there is not one that seeks after God. 12 All have gone out of the way, they have together become unprofitable; there is not one that practises goodness, there is not so much as one: 13 their throat is an open sepulchre; with their tongues they have used deceit; asps' poison [is] under their lips: 14 whose mouth is full of cursing and bitterness; 15 swift their feet to shed blood; 16 ruin and misery [are] in their ways, 17 and way of peace they have not known: 18 there is no fear of God before their eyes.
19 Now we know that whatever the things the law says, it speaks to those under the law, that every mouth may be stopped, and all the world be under judgment to God.
Matthew Henry's Commentary on Romans 3:1-19
Commentary on Romans 3:1-8
(Read Romans 3:1-8)
The law could not save in or from sins, yet it gave the Jews advantages for obtaining salvation. Their stated ordinances, education in the knowledge of the true God and his service, and many favours shown to the children of Abraham, all were means of grace, and doubtless were made useful to the conversion of many. But especially the Scriptures were committed to them. Enjoyment of God's word and ordinances, is the chief happiness of a people. But God's promises are made only to believers; therefore the unbelief of some, or of many professors, cannot make this faithfulness of no effect. He will fulfil his promises to his people, and bring his threatened vengeance upon unbelievers. God's judging the world, should for ever silence all doubtings and reflections upon his justice. The wickedness and obstinate unbelief of the Jews, proved man's need of the righteousness of God by faith, and also his justice in punishing for sin. Let us do evil, that good may come, is oftener in the heart than in the mouth of sinners; for few thus justify themselves in their wicked ways. The believer knows that duty belongs to him, and events to God; and that he must not commit any sin, or speak one falsehood, upon the hope, or even assurance, that God may thereby glorify himself. If any speak and act thus, their condemnation is just.
Commentary on Romans 3:9-18
(Read Romans 3:9-18)
Here again is shown that all mankind are under the guilt of sin, as a burden; and under the government and dominion of sin, as enslaved to it, to work wickedness. This is made plain by several passages of Scripture from the Old Testament, which describe the corrupt and depraved state of all men, till grace restrain or change them. Great as our advantages are, these texts describe multitudes who call themselves Christians. Their principles and conduct prove that there is no fear of God before their eyes. And where no fear of God is, no good is to be looked for.
Commentary on Romans 3:19-20
(Read Romans 3:19-20)
It is in vain to seek for justification by the works of the law. All must plead guilty. Guilty before God, is a dreadful word; but no man can be justified by a law which condemns him for breaking it. The corruption in our nature, will for ever stop any justification by our own works.
