Galatians 3:29-4:7

29If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.

1What 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. 2The heir is subject to guardians and trustees until the time set by his father. 3So also, when we were underage, we were in slavery under the elemental spiritual forces Or under the basic principles of the world. 4But when the set time had fully come, God sent his Son, born of a woman, born under the law, 5to redeem those under the law, that we might receive adoption to sonship. The Greek word for adoption to sonship is a legal term referring to the full legal standing of an adopted male heir in Roman culture. 6Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “ Abba, Aramaic for Father Father.”

7So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.
