Foregathered mobs renouncing God and heaven? (9)

Ross

I believe the answer is:

hereafter

I'm a little stuck... Click here to teach me more about this clue!

'heaven?' is the definition.
(thesaurus)

'foregathered mobs renouncing god' is the wordplay.
I cannot quite understand how this works, but
'god' could be 'here' (Here is an example) and 'here' is found within the answer.
The remaining letters 'after' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'and' is the link.

Can you help me to learn more?

(Other definitions for hereafter that I've seen before include "Hence" , "Life in the future" , "In subsequent parts of legal document" .)
