Jeremiah 30:11 For I am with thee, saith the LORD, to save thee: Though I make a full end of all nations whither I have scattered thee, Yet will I not make a full end of thee: But I will correct thee in measure, And will not leave thee altogether unpunished.
God is with Israel and He will save the nation. He will destroy other nations where He has sent Israel as captives. He will not totally destroy Israel. He will just correct them so that they can serve Him. He will not allow them to get away with sin. He loves them but that love will not tolerate their sin.
God will never finish off Israel. That is why you still see her here as a nation. She will not be finished. She will be used of God. God called them under Abraham and they will be here when His work on this earth is done.
