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. 20 Wherefore by works of law no flesh shall be justified before him; for by law [is] knowledge of sin.
Matthew Henry's Commentary on Romans 3:9-20
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.
