I'm having trouble with this when it seems like ressistance is the result of a derivation of ohm's law assuming constant E-field such that [tex]E = \frac{J}{\sigma} = \frac{V}{l}[/tex], but if E is not constant how can one then relate the ressitance to the current-density J?

A qualitative answer is good enough.
