All of God’s promises are fulfilled in Jesus Christ — He is the New Covenant. The Old Covenant is dead and gone. There are no blessing or promises remaining for those who refuse the New Covenant in Jesus Christ.
Those seeking to justify or bless those who rejected Jesus Christ as the Son of God and Savior, the Messiah, the Blessed One, have sided with the Serpent and his seed.
Every blessing toward Israel and Mount Zion in the Hebrew Scriptures is toward the Church in Jesus Christ: WE are the chosen race, the children of God, a holy nation, the heavenly Jerusalem.
