31 Then what's the advantage of being a Jew? Is there any value in the ceremony of circumcision? 2 Yes, there are great benefits! First of all, the Jews were entrusted with the whole revelation of God. 3 True, some of them were unfaithful; but just because they were unfaithful, does that mean God will be unfaithful? 4 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." 5 "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.) 6 Of course not! If God were not entirely fair, how would he be qualified to judge the world? 7 "But," someone might still argue, "how can God condemn me as a sinner if my dishonesty highlights his truthfulness and brings him more glory?" 8 And some people even slander us by claiming that we say, "The more we sin, the better it is!" Those who say such things deserve to be condemned.

Commentary on Romans 3:1-8
(Read Romans 3:1-8)
The law could not save in or from sins, yet it gave the Jews advantages for obtaining salvation. Their stated ordinances, education in the knowledge of the true God and his service, and many favours shown to the children of Abraham, all were means of grace, and doubtless were made useful to the conversion of many. But especially the Scriptures were committed to them. Enjoyment of God's word and ordinances, is the chief happiness of a people. But God's promises are made only to believers; therefore the unbelief of some, or of many professors, cannot make this faithfulness of no effect. He will fulfil his promises to his people, and bring his threatened vengeance upon unbelievers. God's judging the world, should for ever silence all doubtings and reflections upon his justice. The wickedness and obstinate unbelief of the Jews, proved man's need of the righteousness of God by faith, and also his justice in punishing for sin. Let us do evil, that good may come, is oftener in the heart than in the mouth of sinners; for few thus justify themselves in their wicked ways. The believer knows that duty belongs to him, and events to God; and that he must not commit any sin, or speak one falsehood, upon the hope, or even assurance, that God may thereby glorify himself. If any speak and act thus, their condemnation is just.
