Romans 3:1-4
1 What advantage then has the Jew, or what is the profit of circumcision? 2 Much in every way! Chiefly because to them were committed the oracles of God. 3 For what if some did not believe? Will their unbelief make the faithfulness of God without effect? 4 Certainly not! Indeed, let God be true but every man a liar. As it is written: “That You may be justified in Your words, And may overcome when You are judged.”

So the keepers of the law did not follow it from the heart, yet they have the advantage of having faithfully brought God’s word down through the ages, preserving it for the time the Christ would come. So that tutor points us to grace in a changed life now. All God said is truth; all we say outside of that, of ourselves that is not in agreement with Him is a lie. So we are judged by His word and He is justified by who He is as seen in every word told us. So the Jews as the chosen people point us as each one chosen as His, called out as and into the church of which Christ is the head.
