Good people showing kindness (5)
I believe the answer is:
grace
'kindness' is the definition.
(I've seen this before)
'good people' is the wordplay.
'good' becomes 'g' (abbreviation).
'people' becomes 'race' (**).
'g'+'race'='GRACE'
'showing' is the link.
(Other definitions for grace that I've seen before include "Old batsman" , "Favour - a short prayer" , "'Amazing - - '" , "Elegance; girl's name" , "A girl" .)
