Using words as an effective form of communication is good, but words are best when you put in the proper action to back what you are saying because, as the saying goes "TALK IS CHEAP", anybody who has a voice and the ability to talk can speak but what makes the words reliable is when you have the integrity and dignity to say what you mean and mean what you say, otherwise you are just a noise maker.

Politicians talk but don't do what they say (liars), mad people talk but don't know what they are saying (unsound mind), and even animals like parrots talk too, (imitate sounds), so just because somebody can construct sounds that make sense/ meaning to you don't necessarily mean that the person himself has common sense or know the actual meaning of what they are saying, they could be crazy people who are just copying...
