9 Does this blessedness then come upon the circumcised only, or upon the uncircumcised also? For we say that faith was accounted to Abraham for righteousness. 10 How then was it accounted? While he was circumcised, or uncircumcised? Not while circumcised, but while uncircumcised.” (Romans 4:9–10, NKJV)
The blessedness of which Paul speaks is the forgiveness of sins, given by God as He imputes righteousness to sinners by faith (Rom. 4:5-8). This blessed forgiveness is available to all, and is revealed in the gospel of Jesus Christ (Matt. 28:19-20; Rom. 1:16-17). Those who tried to define forgiveness through keeping the law of the circumcised (the Law of Moses given to the Jews) failed to recognize that Abraham’s faith was counted to him for righteousness while he was uncircumcised (Gen. 15:6). Binding any part of the Law of Moses as essential for salvation is inconsistent with this fact (Acts 15:5-11). When we “walk in the steps of the faith” that Abraham had (while he was still uncircumcised), our faith will also be accounted to us for righteousness. Justifying faith is active (it is a walk), it is obedient. We walk in the footsteps of Abraham when we obey the gospel by believing in Christ, confessing our faith, repenting and being baptized (Jno. 8:24; Rom. 10:9-10; Acts 2:37-38). God is not a respecter of persons. Whoever “fears Him” and “works righteousness” is “accepted by Him” (Acts 10:34-35). We are justified by faith when we believe and obey God like Abraham did (Jas. 2:20-24).
