Thank you. I will first like to say that I have discussed this topic at length in the thread titled "the moral arguement". I will attempt to explain my point of view in a more condensed manner for the sake of time. The first thing I want to ask is simply this, "How can something be defined as
good or
bad/evil ? I would argue that it depends entirely on its purpose.
For example, let's use a knife and a rock as an example. A knife was created with a purpose and that purpose is to cut. Thus, a good knife is one that is sharp and strong so that it can cut well. A bad knife is dull and week. A dull knife is bad because it fails to fulfill its created purpose.
It is also important to note that it is a fact that everything that has ever been created for an intended purpose was created by a being with some level of intelligence. However, something that was created by nature by natural means without a created purpose can be given a purpose by a being with some level of intelligence. In this case we can use a rock as an example. Without a purpose, how can we define what a good/bad rock is? I may say a good rock is shiny and colorful but someone else may say a good rock is hard and flat. The point is simply this, without a clear purpose, it is impossible to clearly define what a good/bad rock is. Now let's just say that a being of intelligence took a rock an put it on a stack of paper and gave it the purpose of being a paperweight. Now we can clearly define if it is a good/bad paperweight based on how well it can hold paper down.
Lets assume that God does not exist and all life (including humans) were created by nature without an intended purpose. Because we are beings with some level of intelligence, we can bestow a purpose onto ourselves. Depending on what that purpose is, our view of what is good or evil will be determined on that purpose we give ourselves.
Let's all assume for the sake of discussion that the God of Abraham does exist. Because He is an eternal being, He was never created with an intended purpose. However, because he is a being with some level of intelligence, he can bestow a purpose onto himself. So whatever purpose He chose to bestow upon himself would be the standard at which he would determine to be good/evil. Also, we would have to assume that mankind and everything else that God created was created for a purpose. So anything that complements our created purpose is good and anything that goes against our created purpose is bad/evil.
In conclusion, the origin of God's moraity is rooted and determined by the purpose he bestowed upon Himself and anything that complements or fulfills God's purpose is good. Anything that goes against that purpose is bad/evil.
