Galatians 4:1-7

Now I mean that the heir, as long as he is a minor, is no different from a slave, though he is the owner of everything. But he is under guardians and managers until the date set by his father. So also we, when we were minors, were enslaved under the basic forces of the world. But when the appropriate time had come, God sent out his Son, born of a woman, born under the law, to redeem those who were under the law, so that we may be adopted as sons with full rights. And because you are sons, God sent the Spirit of his Son into our hearts, who calls “Abba! Father!” So you are no longer a slave but a son, and if you are a son, then you are also an heir through God.
