Romans 4:10-12

Amplified Bible

¹⁰ How then was it credited [to him]? Was it after he had been circumcised, or before? Not after, but while [he was] uncircumcised. ¹¹ He received the sign of circumcision, a seal or confirmation of the righteousness which he had by faith while [he was still] uncircumcised—this was so that he would be the [spiritual] father of all who believe without being circumcised—so that righteousness would be credited to them, ¹² and [that he would be] the [spiritual] father of those circumcised who are not only circumcised, but who also walk in the steps of the faith of our father Abraham which he had before he was circumcised.
