And because you are sons, God has sent forth the Spirit of his Son into your hearts, crying,
Abba, Father.
All Commentaries on Galatians 4:6 Go To Galatians 4
Ambrosiaster
AD 400
He says of the Gentiles who believed in Christ, “You are sons,” having previously been enemies. There can be no doubt that believing Jews were also said to be sons of God, since they had long been called by that name. They had received the name of sons at one time as though by anticipation in order that this sonship might subsequently be understood in Christ, being incomplete without the Spirit. .
