Of course not! Even if everyone else is a liar, God is true. As the Scriptures say about him, "You will be proved right in what you say, and you will win your case in court."
"But," some might say, "our sinfulness serves a good purpose, for it helps people see how righteous God is. Isn't it unfair, then, for him to punish us?" (This is merely a human point of view.)
Well then, should we conclude that we Jews are better than others? No, not at all, for we have already shown that all people, whether Jews or Gentiles, are under the power of sin.
Obviously, the law applies to those to whom it was given, for its purpose is to keep people from having excuses, and to show that the entire world is guilty before God.
But now God has shown us a way to be made right with him without keeping the requirements of the law, as was promised in the writings of Moses and the prophets long ago.
For God presented Jesus as the sacrifice for sin. People are made right with God when they believe that Jesus sacrificed his life, shedding his blood. This sacrifice shows that God was being fair when he held back and did not punish those who sinned in times past,
for he was looking ahead and including them in what he would do in this present time. God did this to demonstrate his righteousness, for he himself is fair and just, and he declares sinners to be right in his sight when they believe in Jesus.
Well then, if we emphasize faith, does this mean that we can forget about the law? Of course not! In fact, only when we have faith do we truly fulfill the law.
