A church removed from god: count on it! (6)

I believe the answer is:

abacus

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

'count on it' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for abacus that I've seen before include "An ancient counting frame with beads" , "frame of sorts" , "Counting machine" , "Manual calculator" , "As a cub (anag)" .)

I've seen this clue in The Sun.
