What is the meaning of [A little help is worth a deal of pity]

This is similar to Actions speak louder than words. It is better to help
persons who are in trouble than to say how sorry you are for them. For
example, when Mrs Pemberton’s kitchen was flooded out by a heavy storm of
rain, Mrs Trulove, who lived next door, was very sympathetic indeed. She was
still telling Mrs Pemberton how grieved she was that such a thing should have
happened to her neighbour, when Mrs Young came across over the road with a
bucket and mop to help Mrs Pemberton to clear up the mess.
