Audio commentary on this verse

Note 1 at Rom. 4:9: Paul had previously shown in this chapter that Abraham's faith was what granted him right standing with God (see notes 3 and 5 at Rom. 4:3, p. 761) and he used a quote from David to verify salvation by grace through faith (see note 10 at Rom. 4:6, p. 762). He now returns to the story of Abraham and uses the very religious act which the legalists were demanding compliance with (i.e. circumcision) to further certify that salvation is by grace through faith.
