I've read Romans through a few times in the last year. I have also read LLoyd Jones comentary on this chapter and disagree with his summary of vs 26.
I think by focusing on the verse rather than the whole of what Romans is saying leads to a wrong conclusion. Thinking it applies only to jews makes us miss the point that all Isreal (God's elect) will be saved. Why does Paul then talk of the fullness of the gentiles coming in; and so all Isreal will be saved, if the gentiles aren't a part of Isreal. The failure of the Jewish nation to see resulted in the salvation of gentiles.
Paul's recognition of what God is doing resulted in that great finish to the chapter in 33-36 because all the Isreal of God will be saved.
