What is Israel's role in bringing the knowledge of God to the nations?

Les explains that Israel's role is to be the vehicle, as he puts it, to bring the knowledge of their God to all the other nations of the world. He reads from Rabbi Shlomo Riskin's article in the Jerusalem Post, which said Abraham had been promised that a nation emerging from his own loins would, against all odds, survive and declare the name of the one God to the world. Les says that is exactly what he has always taught. He ties this to the scope of bringing Israel on the scene, giving them the Abrahamic covenant, making them a nation, placing them in a geographical area of land, and one day having the Messiah come as their King. He notes the Old Testament often speaks in future tense, as with God's promises, "I will make of you a great nation, I will do this, and I will do that."
