Renee, very good post! Have you ever thought of teaching Civics or American History, or Sociology?
I have a few thoughts on this, from my upbringing, church training, and personal observations:
First, the Bible says that "there will be wars and rumors of wars." This is because we were seperated from God and His perfect wisdom and guidance for our lives when Adam and Eve first sinned. Because there are those who do not believe in the concept of sin, heaven, hell, and salvation, we will always have people going about things in their own way, with their own concept of what is right. The only thing is, their neighbors may have another concept that is entirely different (witness Protestants and Catholics in Northern Ireland, and Jews and Arabs in Jerusalem and other regions of the Holy Land).
God did not create us to be unhappy people. Evil, in all its forms, is to blame for the things that make most of us unhappy or ill in spirit. This may result from evil that we do, or that is done to us, or evil that exists in the world.
IMHO, the only way that we can moderate the unrest in the world is to try to be moderate in the things we do and say, and to live the life that we have been taught, by the 10 commandments, from the Bible. That is not to say that in being moderate, we are sissies, or pushovers. We have an obligation to stand up for what we know to be right.
Many religions are tangled up in political ideologies these days. One should never condemn the religion of another, but it may be necessary to condemn the ideals and political views they embrace and espouse. This is where things get sticky, and difficult to live. I would be most interested in hearing what others have to say about how this can be overcome.
