Enjoy embracing one's rescuer (7)
I believe the answer is:
saviour
'rescuer' is the definition.
('saviour' can be a synonym of 'rescuer')
'enjoy embracing one's' is the wordplay.
'enjoy' becomes 'savour' ('savour' can be a synonym of 'enjoy').
'embracing' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'savour' going around 'i' is 'SAVIOUR'.
(Other definitions for saviour that I've seen before include "One who delivers people from harm or danger" , "Round, flat plate" , "preservative type" , "Rescuer" , "people worship Him" .)
