4 but, when the fullness of time came, God sent forth his Son born of a woman, born under the Law,
5 that he might redeem those who were under Law, that we might receive the recognition as sons.
6 Because you are sons, God has sent into our hearts the Spirit of his Son crying Abba, Father.
7 So you are no longer a slave, but a son, and if a son, then also an heir, through God's act.
