Galatians 3:29 - 4:7
And if you belong to Christ, then you are Abraham's descendants, heirs according to the promise. Now I say, as long as the heir is a child, he does not differ at all from a slave although he is owner of everything, but he is under guardians and managers until the date set by the father...Because you are sons, God has sent forth the Spirit of His Son into our hearts, crying, "Abba! Father!" Therefore you are no longer a slave, but a son; and if a son, then an heir through God.
