For you have not received the spirit of bondage again to fear; but you have received the Spirit of adoption, by which we cry, Abba, Father.
All Commentaries on Romans 8:15 Go To Romans 8
Augustine of Hippo
AD 430
The dispensations of the two Testaments are clearly different. The Old Testament is one of fear; the New Testament is one of love. But, you may ask, what is this spirit of slavery? If the spirit of our adoption as sons is the Holy Spirit, then the spirit of slavery to fear is the one which has the power of death. It is because of this fear that those who lived under the law and not under grace were condemned to slavery for their entire lives. Nor is it surprising that those who went after worldly goods received the spirit of slavery by divine providence … for this spirit of slavery has nobody in its power unless he has been handed over by the command of divine providence, since God’s righteousness gives every man his due.
