Read: Romans 3:1-20
Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin. Romans 3:19-20
When you read this terrible description of the human race as God sees it, it is almost impossible for us to believe that God is not going to say, Enough! Wipe them out! If all he sees is wretchedness, misery, evil, deceit, hypocrisy, vulgarity, profanity, slander, and all these evil things that are in every heart — every one without exception — our natural instinct is to say, Then God doesn’t want us. But the amazing thing is that across this kind of verse he writes, God so loved the world that he gave his only begotten Son, (John 3:16a KJV). God did not send the Law to destroy us (and this is very important); he sent the Law to keep us from false hope.
The worst thing that can happen is to be going down a road to an important destination and think you are on the right track and spend all the time necessary to get there only to discover that the road peters out into nothingness. You find you have been on the wrong track and it is too late to go back. That was what was happening. So God, in his loving kindness, has given us the Law to keep us from taking a false path. Though the Law condemns us, it is that very condemnation that makes us willing to listen, so that we find the right path.
Paul says the Law does three things to us: First, it stops our mouth: We have nothing to say. You can always tell someone is close to becoming a Christian when they shut up and stop arguing back. Self-righteous people are always saying, But — but this — but I — yes, but I do this — and I do that. They are always arguing. But when they see the true meaning of the Law, their mouth is shut.
