Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
All Commentaries on Romans 8:12 Go To Romans 8
Ambrosiaster
AD 400
It is right and clear that we are not obliged to follow Adam, who lived according to the flesh, and who by being the first to sin left us an inheritance of sin. On the contrary, we ought rather to obey the law of Christ who, as was demonstrated above, has redeemed us spiritually from death. We are debtors to him who has washed our spirits, which had been sullied by carnal sins, in baptism, who has justified us and who has made us children of God. Commentary on Paul’s Epistles.
