Since last 2-3 years i'm constantly thinking about this question.
Do you know what controls the world? "Word" or "Sword"(in any possible metaphorical meaning of these words).
But if you start the really logical chain of reasoning... So what is the sword? It is the main fisical power. It is the power of the retribution and also last front against the invasion of evil.
Good... But what about the WORD? How often did you need to defend yourself? I am convinced - all your life. Even in the poor countries and also in every the getto of world's modern cities, where the criminality is off-scale, you can be sure that first is the WORD. The second is the sword. But the second is just as a consequence.
The word is not only as a preventer but as big power. No doubts it is mightier.
