Because of our relationship with Christ, we are Abraham’s spiritual descendants, and God’s heirs, no longer like slaves.

Galatians 3:26-29

26 Now all of you Jews and non-Jews are as though you are God’s children because you trusted Christ Jesus. 27 That is, you who began a relationship with Christ when you were baptized identified yourselves [MET] with Christ. 28 If you are believers, it does not matter to God if you are Jews or non-Jews; slaves or ones who are not slaves; males or females, because all of you are as one sort of person because of your relationship with Christ Jesus. 29 Furthermore, since you belong to Christ, you are like Abraham’s descendants because you trust God as Abraham did, and you will possess/receive all that God has promised [MET].
