1 What I am saying is that as long as an heir is underage, he is no different from a slave, although he owns the whole estate.
2 The heir is subject to guardians and trustees until the time set by his father.
3 So also, when we were underage, we were in slavery under the elemental spiritual forcesa of the world.
4 But when the set time had fully come, God sent his Son, born of a woman, born under the law,
5 to redeem those under the law, that we might receive adoption to sonship.b
6 Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba,c 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 forcesd ? Do you wish to be enslaved by them all over again?
10 You are observing special days and months and seasons and years!
11 I fear for you, that somehow I have wasted my efforts on you.
