A Jewish Legalist declares that Israel is the recipient of God’s grace and the Law is the only path to righteousness-salvation.
A Christian rebuttal…
God’s Covenant concerning Messiah and atonement for sin was ordained before the beginning of Time (2 Timothy 1:9-10) and that Gospel Covenant was initiated by God with Abraham (who was NOT a Jew or Israelite) and that Covenant made with Abraham was oriented toward “all the families of the earth”…not just Israel’s children (Genesis 12:3).
“I will bless those who bless you,And I will curse him who curses you;And in you all the families of the earth shall be blessed.” Genesis 12:3
Israel reaping and sowing,
Israel rejected God’s covenants, murdered the prophets sent to them; Israel rejected their Messiah; Israel falsely accused Messiah of blasphemy; Israel conspired with the Roman Authorities to murder Messiah Jesus upon a tree; Israel insisted that Messiah’s blood be upon them and their children; God the Father ordained the Israelite’s to take the Gospel of Messiah to the ends of the Earth but Jacob’s children rejected the Gospel message of grace and continues to cling to a works – self righteousness through Law (Romans 9:31).
Though God entrusted the Law and both Old and New Covenants to Jacob’s children, Israel denied God’s blessing through Messiah; therefore, God gave the Gospel, the New Covenant established in Messiah blood (Matthew 26:28), to the Gentiles (Romans 11:25) and the Gospel will remain in the custody of the Gentiles until such time the fullness of the Gentiles has come in; in fact, it is only the “remnant” of Israel that will escape Judgment in Hell for their rejection of Messiah Jesus (Isaiah 10:22; Romans 9:27).
15 just as the Father knows Me and I know the Father. And I lay down My life for the sheep. 16 I have other sheep that are not of this fold. I must bring them in as well, and they will listen to My voice. Then there will be one flock and one shepherd. 17 The reason the Father loves Me is that I lay down My life in order to take it up again. John 10 (Berean Study Bible)
