Who are the two greatest men in human history according to Les?
The two greatest men in human history are Moses, the giver of the law to the nation of Israel at Mount Sinai, and the Apostle Paul, to whom God gave the doctrines of grace. Both are called the greatest in their respective areas, and both made a statement concerning the nation of Israel.
Les explains that he continually compares, or holds in contraindication, Moses the giver of the law to Israel at Mount Sinai and the Apostle Paul, who he thinks was also at Mount Sinai, where God gave him the doctrines of grace. He calls them two great men in their own respective areas and the greatest two men in all human history. Both make that kind of statement concerning the nation of Israel. Les points this out because much of Christendom, including Roman Catholics and Protestants, thinks God is all through with the nation of Israel, but he insists that little nation is still God's covenant people, even though He has set them aside.
