In Romans 3:19-20 Paul says the following:
Now we know that what things soever the law saith, it saith to them 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 there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Now, I had absorbed the fact that no man has been saved by the works of the law, but there was still a part of me that thought the law technically could justify someone. You know, if some “hypothetical” man was somehow able to keep the law then he would be saved by the law. But what Paul is telling the us here is that this is not true. Instead, he is saying something along these lines:
To those of you who are trusting in the works of the law, you have completely misunderstood its nature. You are like a carpenter who has a too-short board, and who believes that if he measures it over and over again it will somehow get longer. Jesus Christ was not made perfect by the Law, but rather, was perfect all along. All the Law did was allow you to contrast His perfection with your gross unrighteousness. The law, to those who are in sin, is nothing more than a tape measure, but you have been trying to use it as a ladder to God.
What do you think?
