Will All Israel Be Saved?
Verse 26 of Romans 11 is the conclusion to the allegory. Paul says, "And SO all Israel shall be saved." Paul doesn't say, "all Israel shall be saved," but "SO all Israel shall be saved." The word "so" is an adverb of manner. It means in such a way, or in such a manner, all Israel shall be saved. The idea is that they will be saved in the same manner in which they are grafted back into the Olive Tree, through belief that Jesus is the Messiah.
