Then, with special reference to the problem of the Jews, who claimed to be in a privileged position vis a vis the Gentiles because of their descent from Abraham, Paul embarks on a complicated argument, to prove that Abraham was not in effect the classic example of how obedience to the Law made a man right with God. On the contrary, it was because Abraham was pre-eminently a man of faith, who trusted God implicitly, that God accepted him and chose him to be the "father of many nations". This obviously could not mean the Jews only, but must mean all men everywhere who similarly commit their lives to God. Abraham is thus "the father of us all ". Jews and Gentiles, in that he is the prototype of all who are now willing to respond to God as he did, and share his unquestioning faith (4: 1-25).
