Belief as source of hope in troubled times? (6)
I believe the answer is:
theism
'belief' is the definition.
(theism is a kind of belief)
'source of hope in troubled times?' is the wordplay.
'source of' suggests taking the first letters.
'in' is an insertion indicator.
'troubled' is an anagram indicator.
The first letter of 'hope' is 'h'.
'times' is an anagram of 'teism'.
'h' inserted inside 'teism' is 'THEISM'.
'as' is the link.
(Other definitions for theism that I've seen before include "The doctrine or belief in the existence of a God or gods" , "of faith" , "Belief in a creator" , "Belief in existence of a God revealed to man" , "Belief in a deity" .)
