Romans 2:20-25

²⁰and a teacher of the childish, because in the Law you possess the outline of all knowledge and truth.

²¹Why, then, you teacher of others, don't you teach yourself? Do you preach against stealing, and yet steal?

²²Do you forbid adultery, and yet commit adultery? Do you loathe idols, and yet plunder temples?

²³Boasting, as you do, of your Law, do you dishonor God by breaking the Law?

²⁴For, as scripture says — ‘The Gentiles insult God's name because of you’!

²⁵Circumcision has its value, if you are obeying the Law. But, if you are a breaker of the Law, your circumcision is no better than uncircumcision.
