When did Israel lose the Temple and the city and get scattered to every nation?
In about 70 A.D., Israel lost the Temple, the city, and their homeland, and they were dispersed into every nation on earth. This occurred after the nation rejected Him, was set in spiritual blindness, and placed in the same position as the rest of the Gentile world.
Les explains that Israel had been instructed, taught, and nurtured through the Old Testament under the Law and the prophecies, but the nation rejected Him and was dispersed back into the mainstream of humanity from which they were called. They were not dispersed to evangelize as God had intended, but were placed in spiritual blindness and became like the rest of the Gentile world. Les places the loss of the Temple, the city, and the homeland, with dispersion into every nation, at about 70 A.D. He notes that some thirty years before that, Paul was called as the progenitor of the Gospel of Grace and the calling out of a Gentile body of Christ.
