Verse 1
ALL ISRAEL IS NOT ABANDONED V. 1-7
1) “I say therefore," (lego oun) "Therefore I logically say what I say;" I conclude - Paul had shown four things 1) that God had not pledged eternal life unconditionally to all Abraham’s seed, 2) that God was sovereign in mercy grants, 3) that the Old Dispensation was for the purpose of preparing for the later, and that 4) Faith of the Gentiles and unbelief of the Jews was foretold in the Old Testament.
2) "Hath God cast away his people?" (me aposato ho theos ton laon autou) "God has not set aside his people, has he?" The casting off of "his people," the Jews, it has been maintained, and is to be further shown, is not to be forever. It is a long chastening for them as God’s unfaithful wife, not an eternal abandonment, Jeremiah 3:1-14; Amos 9:8-9. As an adulterous wife, natural Israel now has a bill of divorcement.
3) "God forbid," (me genaito) May it not be so assumed;" God will not cast off or abandon his chosen nation forever, Psalms 94:14, though he did and has cut them off for a time of national chastisement, among the nations, as he warned them in their law, Deuteronomy 28:15-68.
4) "For I am an Israelite," (kai gar ego Israelites eimi) "For even I am an Israelite," both nationally and spiritually, a true Israelite, which means "man of God;" If he cut off, even all national Israel forever, he would even cut me off, Paul is asserting. He is an Israelite, a man of God by faith in Jesus Christ, Romans 4:16.
5) "Of the seed of Abraham," (ek spermatos Abraam) "Out of the natural seedline of Abraham"; as such he had the future hope of the restoration of national Israel, as well as a national Jewish heritage. In this he took Holy pride and expressed it, 2 Corinthians 11:22; Acts 26:4-5.
6) "Of the tribe of Benjamin," (phules Beniamin) "Of the tribe (file) of Benjamin," circumcised, marked, and identified as an Israelite of the stock of Israel, tribe of Benjamin, and an Hebrew of the Hebrews, of national descent, Philippians 3:5; Acts 23:1-6.
Tho Israel as a nation was unfaithful to God he abides faithful to his oft-repeated promises that they should possess a fixed land-grant territory in peace and he would send His Son to reign over them. That Israel has not been cut off or set aside forever is the theme of this chapter: Genesis 15:18; Genesis 17:7-8; Luke 1:32-33.
