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
Irenaeus of Lyons
AD 202
Neither do we receive another Holy Spirit, besides Him who is with us, and who cries, "Abba, Father; ".
For those to whom he was writing were not without flesh, but they were those who had received the Spirit of God, "by which we cry, Abba, Father."
