Did God fail if the majority of the Jewish people do not believe in Yeshua? That is the question that Paul answers in Romans 9. The Bible is full of remnants. The majority almost never do what they are supposed to do but there is always a faithful minority that walks in the ways of God. This has always been true of Israel and likewise there are faithful remnants from every nation that have turned to the God of Israel. Did God fail? Absolutely not! And He never will. He calls a remnant from every nation to turn to Himself.
