Galatians 4:4-7

But when the fullness of time had come, God sent his Son, born of a woman, born under the law, in order to redeem those who were under the law, so that we might receive adoption as children. And because you are children, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” So you are no longer a slave but a child, and if a child then also an heir, through God.
