³¹ “His father said to him, ‘Look, dear son, you have always stayed by me, and everything I have is yours.

¹⁰ So she turned to Abraham and demanded, “Get rid of that slave woman and her son. He is not going to share the inheritance with my son, Isaac. I won’t have it!”

⁴ But when the right time came, God sent his Son, born of a woman, subject to the law. ⁵ God sent him to buy freedom for us who were slaves to the law, so that he could adopt us as his very own children.^{[a] 6} And because we^[b] are his children, God has sent the Spirit of his Son into our hearts, prompting us to call out, “Abba, Father.”^{[c] 7} Now you are no longer a slave but God’s own child.^[d] And since you are his child, God has made you his heir.

³⁰ But what do the Scriptures say about that? “Get rid of the slave and her son, for the son of the slave woman will not share the inheritance with the free woman’s son.”^{[a] 31} So, dear brothers and sisters, we are not children of the slave woman; we are children of the free woman.
