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[a] hearts, crying, “Abba![b] Father!” 7 So you are no longer a slave but a child, and if a child then also an heir through God.[c]
