Interesting point. Totally wrong, but interesting.
You're presuming that humanity is only material. Humanity is both material and spiritual. Love is spiritual. There may be an electro-chemical manifestation of it, but love is no more the electro-chemical manifestation of love than you are the physical manifestation of you.
You aren't, you know. Your body isn't the same one that it was 10 days ago. Many of the cells have been replaced. All of the cells will be replaced every 7 years. Assuming you are over 14, you are on your third completely different physical manifestation. Yet you are still you.
If you want to know Truth, you are going to have to step outside the limits of the material.
Shalom.
It seems that more and more our leaders are devoid of moral directions to use as foundations when making laws. This bodes ill for the future of this country. I am amazed at how many Christians feel it is ok to support these politicians. The churches hands are further tied with agreements with the IRS which limit their speech even within the very walls of the church.
It is the lack of morality polluting our society to a point where no one will be safe to live a moral life. In fact if left to continue the idea of right and wrong will be non existent and no compass will be able to determine the way north.
Obviously many so called conservatives and Christians alike will in fact be no different from the most liberal and morally corrupt among us. They will no longer have the capability to discern Good and Evil, Right and Wrong. All it seems to take is a crowd of hyenas to heckle and bay at the moon. and those who stand by and say nothing.
They are rewriting our history and our Bibles and convincing us that it is only a wafer thin morsel as they shove it down our throats. Soon that wafer given in communion to their gods and not ours will choke us as we are not willful enough to resist the lies for the truth.
FACT: There is electro-chemical reactions that create the emotional feelings that man has labeled "love". Because this is something that most people will only see presented on the likes of The Discovery Channel and the like, and given that this has only been discovered in the latter half of the last century, man convinces himself of things such as "meant to be", "the love of my life" and such. A "spiratual love" is much different, and is hard to define or actually "put your finger on it". Our love for God(if one believes that) is spiratual, obviously, because there is no actual entity similar to a person who can illicit the same types of responses as in "scientific love". Every individual will see "spiratual love" differently, while some may not even believe in it.
