12 If you sin without knowing what you're doing, God takes that into account. But if you sin knowing full well what you're doing, that's a different story entirely. Merely hearing God's law is a waste of your time if you don't do what he commands. Doing, not hearing, is what makes the difference with God. 14 When outsiders who have never heard of God's law follow it more or less by instinct, they confirm its truth by their obedience. They show that God's law is not something alien, imposed on us from without, but woven into the very fabric of our creation. There is something deep within them that echoes God's yes and no, right and wrong. Their response to God's yes and no will become public knowledge on the day God makes his final decision about every man and woman. The Message from God that I proclaim through Jesus Christ takes into account all these differences.
17 If you're brought up Jewish, don't assume that you can lean back in the arms of your religion and take it easy, feeling smug because you're an insider to God's revelation, a connoisseur of the best things of God, informed on the latest doctrines! I have a special word of caution for you who are sure that you have it all together yourselves and, because you know God's revealed Word inside and out, feel qualified to guide others through their blind alleys and dark nights and confused emotions to God. While you are guiding others, who is going to guide you? I'm quite serious. While preaching "Don't steal!" are you going to rob people blind? Who would suspect you? The same with adultery. The same with idolatry. You can get by with almost anything if you front it with eloquent talk about God and his law. The line from Scripture, "It's because of you Jews that the outsiders are down on God," shows it's an old problem that isn't going to go away.
25 Circumcision, the surgical ritual that marks you as a Jew, is great if you live in accord with God's law. But if you don't, it's worse than not being circumcised. The reverse is also true: The uncircumcised who keep God's ways are as good as the circumcised - in fact, better. Better to keep God's law uncircumcised than break it circumcised. Don't you see: It's not the cut of a knife that makes a Jew. You become a Jew by who you are. It's the mark of God on your heart, not of a knife on your skin, that makes a Jew. And recognition comes from God, not legalistic critics.
