What does it mean to "rest in the law" and "boast of God" in this passage?

To "rest in the law" means the Jewish people were taking comfort in the fact that they had God’s law and knew His commands. They assumed that simply having this knowledge and belonging to God’s covenant people made them safe. To "boast of God" means they were proud that they knew the one true God, unlike the surrounding nations. The problem is not that they valued the law or knew God, but that they trusted the label and the knowledge while ignoring the obedience and heart change God actually wanted.

Why does Paul ask if teachers who forbid stealing and adultery do these things themselves?

Paul uses these questions to expose hypocrisy. The people he addresses saw themselves as guides for the blind and teachers for others. They spoke against stealing, adultery, and idolatry, yet some of them did the very things they condemned. By asking, “Thou that preachest a man should not steal, dost thou steal?” he is pushing them to see that knowing and teaching right and wrong is not enough. God cares whether we live what we teach. When we don’t, we dishonor God and damage His reputation before others.

What does it mean that God’s name is blasphemed among the Gentiles because of the Jews?

This line means that when the people who claim to belong to God live in open sin and hypocrisy, the nations around them speak badly of God. The Gentiles looked at the Jews, who said they had God’s law and special covenant, and saw them breaking that very law. Instead of being drawn to honor God, they mocked Him, thinking, “If this is how God’s people live, their God must not be worth following.” Paul is warning that our behavior reflects on the God we claim to serve.

In what way does circumcision "profit" only if the law is kept?

Circumcision was the outward sign that a Jewish man belonged to God’s covenant people. Paul agrees it has value, but only if it goes together with obedience to God’s law. If a person is circumcised yet breaks the law, then the sign loses its meaning. It is as if he were uncircumcised, because the outward mark does not match the inward reality. The point is that rituals and signs are not magic. They are meant to picture a life set apart to God. Without that life, the sign is empty.

How can an uncircumcised person "judge" a circumcised lawbreaker in this passage?

Paul imagines a Gentile who is uncircumcised but does what God’s law requires. He says that person’s uncircumcision will be counted as circumcision, and that life of obedience will "judge" the Jew who has the law and circumcision yet breaks it. This does not mean the Gentile sits as a judge in court, but that his obedient life exposes the failure of the one who only has outward signs. It shows that God values real obedience and a changed heart more than birth or religious marks.

What does Paul mean by saying a true Jew is one inwardly?

When Paul says, “He is a Jew, which is one inwardly,” he is shifting the focus from outward identity to the heart. Being part of God’s people is not mainly about family line, national label, or physical signs. It is about an inner work where the heart is turned to God. A true Jew in this sense is anyone whose heart has been changed to love and obey God. Outward things can still have a place, but they do not define who really belongs to God. God Himself, not people, gives this approval.

What is "circumcision of the heart, in the spirit, and not in the letter"?

"Circumcision of the heart" is a picture for an inner cutting away of sin and stubbornness, where the heart is made soft and willing toward God. "In the spirit, and not in the letter" means this work is done by God’s Spirit, not just by following outward rules or letters written on stone or paper. It is not about a physical operation, but about an inward change that leads to real obedience. This kind of heart circumcision is what God praises, even if people do not see or honor it.

Who is Paul talking to when he lists roles like guide of the blind and teacher of babes?

Paul is speaking to Jews who were proud of their role as those who had God’s law. They saw themselves as guides to the blind, lights for those in darkness, instructors of the foolish, and teachers of spiritual children. In other words, they believed they were in a position to correct others, especially Gentiles. Paul is not saying these roles are wrong in themselves, but he is exposing the gap between their high claims and their actual lives. They had the “form” of knowledge, but lacked the obedience that should go with it.

How does this passage challenge religious people today who rely on labels and rituals?

This passage challenges anyone who rests in a religious label, church membership, baptism, or knowledge of the Bible while ignoring obedience from the heart. It warns that knowing the right things, teaching others, or having the right ceremonies does not make a person right with God if their life goes against His will. Like the Jews Paul addresses, people today can boast in having truth but live in ways that dishonor God. The call is to seek a heart changed by God’s Spirit, so that our actions match what we say we believe.
