Galatians 4:4-7

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