You are exactly right and the following scripture tells us plainly that the time of the gentiles will end and God will again turn to his people whom he foreknew.
Romans 11:25-29 (HCSB)
25 So that you will not be conceited, brothers, I do not want you to be unaware of this mystery: A partial hardening has come to Israel until the full number of the Gentiles has come in. 26 And in this way all Israel will be saved, as it is written: The Liberator will come from Zion; He will turn away godlessness from Jacob.
27 And this will be My covenant with them when I take away their sins.
28 Regarding the gospel, they are enemies for your advantage, but regarding election, they are loved because of the patriarchs,
29 since God’s gracious gifts and calling are irrevocable.
paul is addressing the jewish nation/people all the way thru those scriptures, but we now are to read it as many the Church fulfills "all of Isreal shall be saved?"
