I am listening to the most fascinating book on my iPod right now. It's called Blink, and it is by Malcolm Gladwell. You could check it out here on Amazon. The book explores that thing that we do when we "thin slice" input and come to decisions that we would call "going with our gut."
One of the studies Gladwell mentions is about autism. Studying the brain through focused magnetic resonance imaging shows that we use a very sophisticated part of our brain when we are recognizing faces, as compared to a much less sophisticated part of the brain which engages when we are recognizing object. This is why we remember the faces of our friends many years later, but will spend half an hour searching for our luggage at the baggage claim.
Later, I was reading an article in a magazine. Did you know there is actually a special hormone that gets released when we are around people that gives us the "warm fuzzy" about being with our friends? This same hormone turns down the hunger message. It's almost like when we are hungry, part of that hunger is not for food but for family. Think about that feeling you get when you spend time around the table with your friends or your family. That feeling is hardwired to your physiology. Cool, huh?
All of this should not be the least bit surprising to a Christian. God created humans to be in fellowship - with Him and with each other. We are meant to live our lives in community - we are wired for it, specifically.
The next time you feel yourself becoming isolated, make an effort to connect with someone. It's what our Creator intended.
He wired us for community.
