If it's alright with you, I'm going to start calling you Linus. This whole thread reminds me of "Charlie Brown Christmas", arguing over each other, frustration, impatience, to the point that the whole POINT gets lost. And here you stand saying "I know. I know what the dispensation of the grace of God is." And you present the link and your input. Bravo!
The link provided is based on a premise that Paul differed from Peter in not preaching repentance. That is easily refuted just in Acts. Please see my post on that above. In at least three places in Acts Paul preaches repentance.
