I do not think that any one person or individual has all of the power to heal anything in this world. It is not enough money, food, medical help or sufficient people who care enough about others to even try. I believe that each individual "could" have a part in healing our land, if they chose to, but, people do not come together as they should. It is what is called love and people tend to not love their neighbor anymore. You left out the word; hate. There seems to be so much hate. There is also evil, just like the bullying that is going on now that we see in the news.
It is such a hard thing to understand how one person can be so uncaring and mean enough to drive another person to their death and then say it was their fault.
The world will always have suffering, greed, and poverty. I hate to say it, but this is because there will always be people in power and those walking among us, who profess to be concerned about these kinds of things. You know; lip service, telling other what should be done, but doing nothing themselves and doing nothing to stop the rich from getting richer and the poor getting poorer. I am not talking about someone working to become richer, I am talking about all the things like kickbacks in Washington that some government people (no need to call names) get by just being in office and the poor still starving. It is facts, not fiction. Now, that is unfair.
I also believe as I am a Christian, that when a Nation turns away from God, the founder....there can be no cure for anything unless there is a change of heart. Let's just see how many rate downs this gets....
