6 Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba,a Father.”
7 So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.

Paul’s Concern for the Galatians

8 Formerly, when you did not know God, you were slaves to those who by nature are not gods.
9 But now that you know God—or rather are known by God—how is it that you are turning back to those weak and miserable forcesb ? Do you wish to be enslaved by them all over again?
