True Jews!

"The circumcising of the heart by the Spirit was considered to be an eschatological work that would occur in the days when redemptive history was being fulfilled. The circumcision of the heart by the Holy Spirit signifies the inauguration of redemptive history. God is now fulfilling his saving promises. That which physical circumcision anticipated, the circumcision of the heart, is now a reality through the Holy Spirit. Since true circumcision and genuine Jewishness are not external matters but the result of the Spirit's work, it follows that Gentiles are part of God's people - true Jews! God's saving promises made to Abraham are now becoming a reality."

-Thomas Schreiner, Paul, Apostle of God's Glory in Christ, 81.
