Galatians 4:1-7

Now I say, as long as the heir is a child, he differeth nothing from a servant, though he be lord of all; But is under tutors and governors until the time appointed by the father: So we also, when we were children, were serving under the elements of the world. But when the fulness of the time was come, God sent his Son, made of a woman, made under the law: That he might redeem them who were under the law: that we might receive the adoption of sons. And because you are sons, God hath sent the Spirit of his Son into your hearts, crying: Abba, Father. Therefore now he is not a servant, but a son. And if a son, an heir also through God.
