something to simple consider, for those who haven't committed everything they've got to dispensational millennial theology yet...if DISPY THEOLOGY IS WRONG, it's really wrong:
III. Two Passages Considered Crucial by Millennialists
A. ROMANS 11 (esp. v. 26: "And so all Israel will be saved")
1. EVEN IF A FUTURE CONVERSION OF ISRAEL PREDICTED, THIS IS NOT PROOF OF PREMILLENNIALISM
2. NOWHERE IN ROM 9-11 DOES PAUL SPEAK OF A RETURN OF THE JEWS TO THEIR LAND OR AN EARTHLY REIGN OF CHRIST FROM JERUSALEM
3. BUT DOES PAUL EVEN PREDICT A FUTURE CONVERSION OF NATIONAL ISRAEL?
a. THE CONTEXT OF ROM 9-11: Paul is wrestling with the issue of how the Messiah, foreseen in the OT as a great blessing to the Jews, could have been rejected by them.
b. ROM 9:1-5 ACKNOWLEDGES THAT ISRAEL WAS CHOSEN BY GOD AND POSSESSED THE HIGHEST SPIRITUAL BLESSINGS
c. ROM 9:6-7 REJECTS THE FALSE IMPLICATION THAT GOD HAS BEEN UNTRUE TO HIS PURPOSE FOR ISRAEL. His explanation: not all who are descended from Israel are Israel.
d. ROM 9:8 - 10:21: THERE FOLLOWS A SERIES OF ILLUSTRATIONS that "mere physical descent from Abraham did not guarantee the possession of the blessings promised to Abraham."
(1) Ishmael (9:8-9)
(2) Esau (9:10-18)
(3) In 9:24-26, Paul recalls that God told Hosea that He would choose others who were not his people to be "my people." They would be called "sons of the living God." (Hosea 2:23, 1:10)
(4) In 29:27-29 he cites Isaiah 29:16 and 45:9 as evidence that not all of Israel would be saved, but only a remnant.
(5) In 10:19 he cites Deut 32:21 as evidence that God would make Israel envious "by those who are not a nation." (6) In 10:20-21 he cites Is 65:1-2 in defense of God’s present choice of the Gentiles.
e. ROM 11:1-10 REAFFIRMS THAT GOD HAS NOT REJECTED HIS PEOPLE: A BELIEVING REMNANT REMAINS
(1) Paul cites himself as an example of a believing Jew (11:1)
(2) Israel’s situation is no different than in Elijah’s day when a remnant was chosen. (3) UPSHOT: GOD HAS BEEN TRUE TO HIS PURPOSE IN ELECTION, FOR ELECTION IS NOT COEXTENSIVE WITH THE WHOLE NATION. (Rom 11:7)
f. ROM 11:11, TRADITIONALLY VIEWED AS A TURNING POINT IN PAUL’S ARGUMENT, IS NOT.
(1) Prior to 11:11, Paul stated that God’s rejection of the Jews is not total. After 11:11 he seems to say that neither is it final. Rom 11:12, 15, 25-26 foresee widespread conversion of Jews.
(2) YET THIS CONVERSION OF JEWS IS NOT FUTURE - IT IS CONTEMPORANEOUS WITH THAT OF THE GENTILES, AND WILL BE TO THE END
(a) "Just as you who were at one time disobedient to God have now received mercy as a result of their disobedience, so they too have now become disobedient in order that they too may now receive mercy as a result of God’s mercy to you." (11:31)
(b) I.e., Paul conceives of the Jews’ conversion occurring in the present as a result of the Gentiles’ conversion, which incites them to envy. Cf. 10:19. (c) While this did not happen in Paul’s day, the process of Gentile conversion and Jewish response will continue until "the full number of the Gentiles has come in. And so all Israel will be saved" (11:25-26)
(3) CONCLUSION: WHEN PAUL TALKS ABOUT THE CONVERSION OF ISRAEL, HE IS NOT SPEAKING OF A FUTURE CONVERSION AFTER THAT OF THE GENTILES, BUT A PRESENT ONE IN RESPONSE TO THE GENTILES.
