Why has salvation come to the Gentiles?
Salvation has come to the Gentiles through Israel's fall—their rejection of the Messiah and the Old Testament covenant promises. When Israel crucified their Messiah and refused His offer of the King and the Kingdom, that stumbling caused salvation to come to the Gentiles, as Romans 11 explains.
Les teaches that Israel's fall was not total, but it was the means by which salvation reached the Gentiles. He points to Romans 11, where the question is asked whether Israel stumbled that they should fall, and the answer is no way. Les explains that Israel experienced this fall when they crucified their Messiah and rejected His offer of the King and the Kingdom. Through their fall, through their rejecting the Old Testament covenant promises, salvation has come to the Gentiles. He then directs the audience to Galatians chapter 3, urging them to learn how to study, not just read.
I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
