Romans 4:10

10 How then was it reckoned to him? Was it before or after he had been circumcised? It was not after, but before he was circumcised.

Romans 4:10 In-Context

8 blessed is the one against whom the Lord will not reckon sin."
9 Is this blessedness, then, pronounced only on the circumcised, or also on the uncircumcised? We say, "Faith was reckoned to Abraham as righteousness."
10 How then was it reckoned to him? Was it before or after he had been circumcised? It was not after, but before he was circumcised.
11 He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the ancestor of all who believe without being circumcised and who thus have righteousness reckoned to them,
12 and likewise the ancestor of the circumcised who are not only circumcised but who also follow the example of the faith that our ancestor Abraham had before he was circumcised.
