Various different means of being delivered (7)
I believe the answer is:
saviour
'means of being delivered' is the definition.
(deliver can mean to save or rescue)
'various different' is the wordplay.
'different' indicates an anagram.
'various' is an anagram of 'SAVIOUR'.
(Other definitions for saviour that I've seen before include "preservative type" , "Mankind's deliverer (The Scaffold's Lily 15)" , "Deliverer or redeemer" , "people worship Him" , "Rescuer" .)
