Blessing; a resource (5)
I believe the answer is:
asset
I believe this is a double definition.
'blessing' is the first definition.
(I've seen this before)
'a resource' is the second definition.
(I've seen this in another clue)
(Other definitions for asset that I've seen before include "Part of motor vehicle wheel" , "valuable sort" , "Something of value, worth having" , "Something well worth having" , "It's an advantage to declare" .)
