If you desire or pray for the healing of loved ones, nations, communities, ect. by using words, then you are the one responsible to make it happen. Don't assume someone will do it for you.
If you do not like that homeless live just a few blocks away from your safe home then get to work to create a safe home for them to call home. If you do not like the idea of a kind and gentle person (no different than you) dying from starvation or dyhydration then remember you have the power and the resources to change the way we feed and quench the thirst of all human beings.
"And the king will answer them, just as you did it to one of the least of these who are mebers of my family you you did to me." (Mt. 25:45)
Imagine, just for a moment, Jesus is a King who decides who lives in his kingdom and who is cast out based simply on the merits of how one treats the king's subjects. Does that not suggest there is considerable weight on how we treat the Jesús' of the world?
Likewise, our freedom of speech weights heavily on our actions. Violent words beget more violence, but loving words create more love. Action produces a re-action. Words are an active participation, not simply sounds we utter. While you are free to speak, you are also free to remain silent. And even in a free democracy, both require a sacrifice of one kind or another.
The Freedom of Life is not free. Nor is the freedom of speech. Like those who cannot afford to speak freely without the fear of persecution, there are those in our free country who cannot afford to live freely as so many of us live. They need our help,not just our words. More often than not, they need a helping hand, and not simply a government handouts, although that is a step.
The action of human kindness from those who are willing to put their words into action creates the re-action of transformation. An open mouth should be like an open heart, free to give love to those in need and take love from those whom we seek love of our own.
