Lost, a rector finds God (7)
I believe the answer is:
creator
'god' is the definition.
(I know that Creator is a god)
'lost a rector' is the wordplay.
'lost' indicates anagramming the letters.
'a'+'rector'='arector'
'arector' with letters rearranged gives 'CREATOR'.
'finds' acts as a link.
(Other definitions for creator that I've seen before include "Originator - God" , "Someone who makes something" , "Person who makes or invents things" , "Inventor" , "Maker" .)
