Galatians 4:1-7 NIV

[1] What I am saying is that as long as an heir is underage, he is no different from a slave, although he owns the whole estate. [2] The heir is subject to guardians and trustees until the time set by his father. [3] So also, when we were underage, we were in slavery under the elemental spiritual forces of the world. [4] But when the set time had fully come, God sent his Son, born of a woman, born under the law, [5] to redeem those under the law, that we might receive adoption to sonship. [6] Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba, Father.” [7] So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.
