To them belong the patriarchs, and from their race, according to the flesh, is the Christ, who is God over all, blessed forever. Amen.
Romans 9:5 ESV

The patriarchs…their race… These are unambiguous references to physical descent. The bloodline matters whether we like it or not, whether it fits our theology or not. Yeshua is a Jew by genetic and cultural heritage. There is no other way that he could be heir of David and King of the Jews.
