Galatians 4:4-7

4But when [in God’s plan] the proper time had fully come, God sent His Son, born of a woman, born under the [regulations of the] Law,

5so that He might redeem and liberate those who were under the Law, that we [who believe] might be adopted as sons [as God’s children with all rights as fully grown members of a family].

6And because you [really] are [His] sons, God has sent the Spirit of His Son into our hearts, crying out, “Abba! Father!”

7Therefore you are no longer a slave (bond-servant), but a son; and if a son, then also an heir through [the gracious act of] God [through Christ].
