Without yet having checked the Romans cite, I agree with almost all johnjtr just said. Not only is that how I think Christianity would be without Paul; it is also, for the most part, how I personally believe.

One difference:

Because of that G-d can have mercy upon all. (Emphasis added.)

IMO God's grace does already extend toward all.
