Did God forget the Gentiles while He was focusing on Israel in the Old Testament?
No. Although God focused primarily on Israel from Abraham into the New Testament, with exceptions, He never lost sight of the Gentile river of humanity. Israel was to be a light to the Gentiles and God's salvation to the end of the earth, and could have evangelized them as a kingdom of priests.
Les explains that from Abraham until into the New Testament God was looking at the Jew only—with exceptions—but He had not lost sight of the Gentile river of humanity. God had the whole program laid out so Israel could have evangelized the Gentiles and brought them to a knowledge of Jehovah, and could have been a nation and a kingdom of priests. The passage says God would also give Him as a light to the Gentiles, to be salvation to the end of the earth. Isaiah 59:20 speaks of the Redeemer coming to Zion and to those in Jacob who turn from transgression; Israel's spiritual climate would have to be all believers.
