Yes, but to be in the dead center, there has to be something on either side of you. And the opposite of what is on the left side, would be on the right side. I believe the point that Jesus was trying to make was about the actions of a human being. Which would make him a psychoanalyst. Is heat the action of a human being? How about light? Or time? None of these are actions of a human being. And as far as religion is concerned, that's all we are really talking about. Right and wrong actions. This is what makes something a sin - when it is a wrong action. But wrong to who is the basic problem. What one culture deems correct, another culture deems bad and evil. This is the basic problem in determining sin. Who is right?
