When I look back on things that I considered to be "sinful", I look back at a person who was short sided and petty. I then wonder, how can I have ever thought these acts would benefit me or anyone else in the least? What was I thinking? Was I stupid? Was I nuts?
For me, sin occurs when we don't have the ability to see the "Big picture", which none of us are 100% capable of doing, and not relying on the one power that can. Our thoughts are then turned inward as we selfishly focus only on ourselves. It certainly simplifies things to our liking, but it makes us go awry. This can occur from various sources such as the lack of intellectual capacity and/or perhaps a lack of emotional well being etc. All in all, it is a rather pathetic state. It is like watching a fatherless child trying to rear himself.
