Galatians 4:1-7

But I say that, during the time an heir is a child, he is no different from a servant, even though he is the owner of everything. For he is under tutors and caretakers, until the time which was predetermined by the father. So also we, when we were children, were subservient to the influences of the world. But when the fullness of time arrived, God sent his Son, formed from a woman, formed under the law, so that he might redeem those who were under the law, in order that we might receive the adoption of sons. Therefore, because you are sons, God has sent the Spirit of his Son into your hearts, crying out: "Abba, Father." And so now he is not a servant, but a son. But if he is a son, then he is also an heir, through God.
