Galatians 4:4-7

When the time came to completion, God sent His Son, born of a woman, born under the law, to redeem those under the law, so that we might receive adoption as sons. And because you are sons, God has sent the Spirit of His Son into our hearts, crying, “Abba, Father! ” So you are no longer a slave but a son, and if a son, then an heir through God.
