Romans 4:9, 11, 13, 22

Is this blessing only for the circumcised, or also for the uncircumcised? For we say, “FAITH WAS CREDITED TO ABRAHAM AS RIGHTEOUSNESS.”

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

For the promise to Abraham or to his descendants that he would be heir of the world was not through [observing the requirements of] the Law, but through the righteousness of faith. [Gen 17:4-6; 22:16-18]

Therefore his faith WAS CREDITED TO HIM AS RIGHTEOUSNESS (right standing with God). [Gen 15:6]
