Maybe it's just me, but I'm amazed how with all the various ways we have to communicate with each other, we still seem to communicate very little. With email, cell phones, land lines and social websites like Facebook, there's a lot of different ways for us to communicate back and forth with one another. On the other hand, it also makes for new and different ways for us to be rude and ignore each other.
When email first started, it was reliably unreliable at best. One could easily use the excuse "Oh I didn't get that email." and you could be reasonably sure that was true. But now, with email being more reliable, emails do not get lost in cyberspace nearly as often. The ones that truly bother me though are the ones that get ignore on social websites. The likelihood of a message getting lost on a site like Facebook is very little. The way the systems work on these things, it's not very likely at all that someone didn't get a message sent to them. The real reason they don't get responded to is that the message was ignored.
Perhaps I'm over sensitive, but it seems to me that plain old common courtesy should reign in these matters. A simple short message in reply would be by far more courteous than to not reply at all. When that is done, what people are truly saying to the person who sent that message is, "You're not worth my time to answer." Ask yourself ... would you do that to some one face to face? Then why do it via electronic mail or messaging? It's just plain rude and can be construed as being mean-hearted.
We will be held accountable for our actions one day. Remember there are sins of omission and sins of commission. Those you do and those when you didn't do something, but should have. How can we possibly be considered loving and worth listening to if we can't take the few seconds it takes to answer an email. I know ... "If I answered all the emails I get, that's what I'd be doing all day!" Perhaps, perhaps not. If people are truly what matters to Jesus, even the littlest thing like an email matters.
