31 Then what advantage has the Jew? Or what is the value of circumcision? 2 Much in every way. To begin with, the Jews are entrusted with the oracles of God. 3 What if some were unfaithful? Does their faithlessness nullify the faithfulness of God? 4 By no means! Let God be true though every man be false, as it is written, "That thou mayest be justified in thy words, and prevail when thou art judged." 5 But if our wickedness serves to show the justice of God, what shall we say? That God is unjust to inflict wrath on us? (I speak in a human way.) 6 By no means! For then how could God judge the world? 7 But if through my falsehood God's truthfulness abounds to his glory, why am I still being condemned as a sinner? 8 And why not do evil that good may come? --as some people slanderously charge us with saying. Their condemnation is just.
9 What then? Are we Jews any better off? No, not at all; for I have already charged that all men, both Jews and Greeks, are under the power of sin, 10 as it is written: "None is righteous, no, not one; 11 no one understands, no one seeks for God. 12 All have turned aside, together they have gone wrong; no one does good, not even one." 13 "Their throat is an open grave, they use their tongues to deceive." "The venom of asps is under their lips." 14 "Their mouth is full of curses and bitterness." 15 "Their feet are swift to shed blood, 16 in their paths are ruin and misery, 17 and the way of peace they do not know." 18 "There is no fear of God before their eyes."
19 Now we know that whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God.

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.
