That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
All Commentaries on Romans 8:4 Go To Romans 8
John Chrysostom
AD 407
Paul shows that it is not only binding on us to keep ourselves from evil deeds but also to be adorned with good. For to give the crown is his prerogative, but to retain it is your responsibility. For Christ has fulfilled the righteousness of the law on your behalf so that you are not subject to its curse. So do not betray so great a gift, but keep this great treasure under guard. For here Paul shows us that baptism will not save us if afterward we fail to display a life worthy of that gift. This is why he returns to the law and defends it. For once we have become obedient to Christ, we must use all ways and means so that its righteousness, which Christ fulfilled, may abide in us and not come to naught.
