God has a revolutionary style (7)
I believe the answer is:
panache
'style' is the definition.
(I know that style can be written as panache)
'god has a revolutionary' is the wordplay.
'god' becomes 'pan' (Pan is an example).
'has' says to put letters next to each other.
'revolutionary' becomes 'Che' (Che Guevara the Marxist revolutionary).
'pan'+'a'+'che'='PANACHE'
(Other definitions for panache that I've seen before include "Distinctive elegance" , "'Dash, flair (7)'" , "Grand manner, theatricality" , "Flamboyant sense of style" , "Style, elan" .)
