Did Jesus restrict membership into the new covenant and what are the implications of being excluded from it?

Which version or rewrite are you looking into? You mention 3 of the 4 new testament authors but these were selected from some dozen others. Why then does this new book not contain all of them? And which sin do you refer to? The sin have done recently, or that with which you were born? Can you not understand this is all ridiculous nonsense? And so designed to confuse you.
