Now we know that whatever the law says, it says to those who are under the law, that every mouth may be stopped, and all the world may become guilty before God. Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.
What It says Romans 3:19-20 belies what anyone can say about the justification by God’s law. The Ten Commandments are God’s standard, which is virtually impossible to be reached by any human being. Therefore, no one can be exempt from judgment because all without exception have violated them. The function of the Law of God is to bring to humanity the knowledge of sin. At the same time conveys the information that we are all unable to justify ourselves before God by our works.
It is unfortunate that many modern preachers do not adequately teach the function of the law of God. Now, in contrast, what it is preached about in the past. For example, the seventeenth-century English preacher John Bunyan (1628-1688) said””The man who does not know the nature of the Law cannot know the nature of sin.” Undoubtedly Bunyan was paraphrasing Romans 3:19-20.
A couple of centuries later, another Englishman John Charles Ryle (1816-1900) said: “Let us expose and emphasize the Ten Commandments, and show the length, width, depth, and height requirements of them.” Ryle put things in a more systematic way. The Ten Commandments is the standard for measuring the quality of human behavior to God. And those requirements are unreachable for our humanity.
Let’s give some emphasis to Romans 3:19-20 when it says that every mouth may be stopped, and all the world may become guilty before God. There are individuals who fill their mouths saying they are good people. When somebody asks them if they deserve to go to heaven immediately they answer yes because they are good people. The intent of the law of God is close their mouths and let anyone quite clear that there is nobody in this world that is free of judgment of God.
Another notable part of Romans 3:19-20 is by the deeds of the law no flesh will be justified in His sight. The justification according to the Bible is by grace, not by works. So no one can boast of his goodness to gain salvation. But grace is not a license to sin. Therefore, the Law of God leads us to identify our sin, while grace cleanses us from sin through faith in Jesus Christ. If we don’t have a full awareness of our sin through the Law, it is impossible to appreciate the grace.
The American pastor John MacArthur (1939) said. “The grace of God cannot be faithfully preached to unbelievers while the law is not preached and be exposed the corrupt nature of man.” Therefore, the law discover our filth for we can be cleansed by grace. God bless you.
