It is those Jews and non-Jews who trust Christ who are Abraham’s spiritual descendants, because those who seek to be justified by obeying the laws that God gave Moses are condemned by God.

Galatians 3:6-12

6 What you have experienced is as Moses wrote in the Scriptures about Abraham. He wrote that Abraham trusted God, and as a result, he was considered as being righteous {God erased the record of his sins}. 7 You must realize, therefore, that it is those who trust in what Christ has done who are like Abraham’s descendants [MET] because they trust in God as Abraham did. 8 Furthermore, God planned beforehand that it was when non-Jews trusted him that he would erase the record of their sins. Moses wrote in the Scriptures [PRS] this good message that God told Abraham: “Because of what you did, I will bless people in [MTY] all nations.” 9 So, we can conclude that it is those who trust in what Christ has done whom God blesses. That includes all non-Jews and Jews who trust him, along with Abraham, the one who trusted him long ago. 10 That is, God will eternally punish all those who mistakenly think that God will erase the record of their sins as a result of their obeying the laws that God gave to Moses. What is written in the Scriptures is that God will eternally punish everyone who does not continuously and completely obey all the laws that Moses wrote. 11 But God has declared that if he erases the record of anyone’s sins, it will not be as a result of their obeying the laws God gave Moses. This is evident because the Scriptures say, “Every person whose record of sins God erases because that person trusts God will live spiritually.” 12 But when God gave his laws to the Jews, he did not say that a person must trust him. Instead, God said that it is those who obey all God’s laws, continuously and completely, who will live.
