Actually, actions speak louder than words can be just on the same level of wisdom as words speak louder than actions. Though, more emphasis is put on the former than the latter. Growing up as a child this was always the case. I was taken care of medical wise, and so forth. Of course actions are a sign of love. But when you're a child and you're only "seeing actions" you don't know how to interpret that as love just the act of being taken care of. When babies are infants, the child reacts to their mother's tone of voice. They say talk to the child when they are growing in the mother's womb. Something about what's said and how sooths the child. It's the same vis versa. When there is negativity in the words, actions become distorted. "My mother is doing this for me but she never says she loves me" type of thing.
Interestingly enough I found this online.
