In Christ Jesus neither circumcision nor uncircumcision counts for anything, but a new creation. Paul clears away religious categorization here. In the New Covenant, what matters is not which label you carry but that you are newly created.
Accusation often works with old categories: what you were, what you did, which group you belong to. But God sees a new creation. The old standards no longer apply.
When an inner voice tries to pin you to old mistakes today, you may answer: That is no longer who I am. I am a new creation in Christ.
