Why did God the Father remove the promise of the Gospel from Israel as His purveyors of Truth and give that promise to the Gentiles?
The Gospel of Jesus Christ was ordained “before the beginning of Time” (2 Timothy 1:9-10) as the battle strategy by which the Son of God, Jesus Christ, would “destroy the works of the Devil” (1 John 3:8b) as our entire creation is the resultant of a rebellion led by the Devil and that rebellion necessitating extrication from the Kingdom (Luke 10:18) where nothing impure is permitted to exist (Revelation 21:27).
God the Father, during the creation narrative and immediately subsequent to the Fall, demonstrated, articulated, that He would defeat His nemesis, Satan (Ezekiel 28:11+), through His own selfless love apart from the works of humankind (Genesis 3:15; Genesis 3:21-fig leaves); unfortunately, God’s plan to set apart a special people group through whom He would codify His Law, Law being the arbiter of free will, and ultimately introduce Himself in flesh was stymied by free will which manifest in the defilement of the Adamic and Noahic generations via their obscene perversity and compromise with the Devil (Genesis 6); therefore, God destroyed all but eight by water and began anew through Noah.
Soon, God commissioned Abraham as a Patriarch of a people group through whom He would reveal Himself to mankind and ultimately destroy the works of the Devil via selfless love and sacrifice via Messiah. To this end, God made a covenant with Abraham and promised Abraham that through him every family of the earth would be blessed (Genesis 12:3); this, referencing the Gospel of Jesus Christ that would be the property, the divine possession, of Abraham’s seed and through these people God originally planned to proselytize the entire Earth with the Gospel via the Great Commission (Matthew 28:16-20; Jeremiah 31); in fact, Jesus clearly articulated the truism that He had come only to the lost sheep of Israel (Matthew 15:24-25).
Unfortunately, Israel’s children rejected the Gospel message; Israel’s children rejected their Messiah and falsely accused Him of blasphemy; Israel’s children conspired with the Roman authorities to murder their Messiah upon a tree; Israel’s children demanded that Messiah’s blood be upon them and their children; therefore, God ultimately took the Gospel intended for Israel’s children and gave that Gospel and the responsibility for the Great Commission to the Gentiles until such time the fullness of the Gentiles entering the Kingdom will have come to fruition (Romans 11:25; Acts 13:64).
For this reason, the Jew, the Israelite, continues to reject the Gospel of Jesus Christ, Israel continues to reject their Messiah and for this reason i.e. “unbelief,” only a remnant of Israel’s children will escape the “second death” in Perdition (Isaiah 10:22; Romans 9:27); that remnant being those who witness Messiah’s second-advent and wail and mourn for the One they have pierced and subsequently believe in Jesus as their Lord and Messiah who died for them (John 19:37; Zechariah 12:10).
Though man’s free will reigns paramount, God’s eschatological Plan is undeterred via His omnipotence. God works through and around our personal decisions, our free will, to bring His eschatological will to fruition. God’s will be done! Amen!
