Cease resistance and donate more (4,2)
I believe the answer is:
give up
'cease resistance' is the definition.
(thesaurus)
'donate more' is the wordplay.
'donate' becomes 'give' (I've seen this before).
'more' becomes 'up' (I can't explain this - if you can you should believe this answer much more).
'give'+'up'='GIVE UP'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for give up that I've seen before include "Abandon; cede" , "Resign" , "Surrender informally, cease to try" , "Throw in the towel" , "Surrender or abandon hope" .)
