Feeding our selfishness and lusts at the expense of others-- James 4:1 "What causes quarrels and what causes fights among you? Is it not this, that your passions are at war within you?" http://bible.cc/james/4-1.htm
I think people are feeling fearful and a bit insecure in the world. No one seems to share a common goal and no one seems to want to make an effort to work together to make anything better. Some feel distrustful of the unfamiliar and unknown. Fearful people can be panicky and dangerous. I hope we can pull it together soon.
There with out question many reasons why there is division in the world. One thing I am sure with is we live in different places/ environments. Depending on how you look at divisions, our different surroundings/ environments has influenced us to diversify resulting in may people to be divided. This is one perspective, as division of people has many meanings.
there is something in history that is called "first mention". i could recite some first mentions but then they might be debated (i know i have challenged them at times). individually, politically, culturally, globally. there are three areas that create the most stringent walls to unity: pride; provision; power. sometimes these are even guised in "peace". in short the key to the answer is in a word "self-ish-ness". on the other hand to be of one accord.. well that is another story.
I don't know if the world is any more divided now than before, or if it's just more evident now because the world has become so technically advanced in all areas, including communication. The world is ruled by man (different powers and governments) and not God, and that's why there's so much division.
Great question. Unfortunately, far too many don't grasp the simple answer - which is that those relatively few in "power" create and perpetuate "division" among the "people" in order to retain power over them. Remember "Together, we stand - divided, we fall"? They are counting on us being divided, or their power is "gone". And they will use any horrific device they can come up with to keep us where they want us - race, religion, class, gender, income etc. - anything they can possibly use in order to pit us against each other - because the more we are against each other - the more power they have over all of us. It's the age old strategy that has worked time and time again throughout human history - "DIVIDE AND CONQUOR!" - and we still don't get it - do we? It's way past time we did!
