One thing I think might encourage hardheartedness, and there's a Bible statement that seems to back this up....the world becoming more populated and spread out.Because things become more impersonal, and so others, considering you to be "just a stranger" to them,have no great conscience about what they do to you.Is this true, that with overpopulation, and the world being more "spread out" , that the feeling of brotherhood has died?Well, what does the Bible say?In Genesis we read, "And it came to pass, when men began to multiply on the face of the Earth and daughters were born unto them,that the sons of God saw that the daughters of men that they were fair and they took to them wives, all of which they chose,'followed by God shortening the lifespan,and not too many verses down, the Flood.Now, check out,"WHEN MEN BEGAN TO MULTIPLY,not noting this when there were just a handful of people earlier on {That's one sin.}.Also, several years ago, in my teenage days, I lived in a small town in New York state, and because everyone pretty much knew each other,there's was more a feeling of brotherhood than this cold attitude we see in the "larger world" now. Sure, there were sinners there, but everyone knew each others "bag", so they didn't have to be paranoid of "everybody", like in the "larger world"Everything was on a smaller scale.When there's too many people, people start generalizing, because they don't know you well, they might fit you into a certain category.{Whereas in a smaller circle, they know "who's who" more.}Then in the past compared to now, because the population was somewhat less, things were more personalized.Now, you're "just another number".and your personal feelings don't matter.So!! Do I have a certain point,that, because of overpopution, peoples "brotherly love" attitude"cools off", and this callous attitude develops,which is somewhat sinful? I would think so, also,the verse"WHEN MEN BEGAN TO MULTIPLY...".
