Galatians 4:4-7
4:4 But when the appropriate time had come, God sent out his Son, born of a woman, born under the law,
4:5 to redeem those who were under the law, so that we may be adopted as sons with full rights.
4:6 And because you are sons, God sent the Spirit of his Son into our hearts, who calls “Abba! Father!”
4:7 So you are no longer a slave but a son, and if you are a son, then you are also an heir through God.
