How would your life change if you knew God didn't exist?

We are all confronted with a life of constant churn, trying to survive to the next day. Day after day I'm faced with moral challenges, dealing with things such as need, wants and desires. I'm confronted with an advertisement system which tells me "if it feels good, do it" but a struggle with a moral consequence to that action. I was taught that stealing, slander, cheating on my wife, murder, envy, not honoring my parents, and respectful speech of God is the moral standard set down by my Christian worldview. When I'm needing money, I don't rob a bank because of my moral standard.

Does a belief in God truly affect our moral decisions? According to The Pew forum on Religious and Public life 88% of Americans are sure or fairly sure that God exists. 57% of Americans feel that you need a belief in God to have a moral standard. The funny thing is the generational gap trend is showing that this is also a changing perspective. In the US 61% of the people over the age of 40 that were surveyed and only 51% of the people between the ages of 18-39 said there must be a belief in God to be moral. That means the trend is moving to a belief system which doesn't rest upon a higher moral authority.

In my last blog I talked about altruism, and how I don't believe that any human is selfless. I think that from the infant to the oldest of us, we are all selfish by nature. When we were born, we didn't desire the best for our parents, all we thought about was our needs: Food, warmth, and comfort. My argument is that if we are left to our natural desires, without some kind of external influence in our lives, we would have no moral standard. Even those who claim "there is no god", live under the shadow of His presence.

So lets just pretend we live in a world where God never existed, there never was a god. What would this world look like, how would it function, what would be the norms and morals of this society? What would the standard of human value be based upon? What is the worth of a person, merely what they are capable of producing? What would be the purpose of living?
