The belief in the Abrahamic god Yahweh (Jewish, Christian, Islamic) is one that assumes omnipotence and omnipresence. A Christian will most often say that god is everywhere, everything, and knows all that there is to know. They therefore assert that the god of Abraham knows everything that will happen at every moment in time and has always known this information.
Thus, it is completely logical and reasonable to conclude that he knew the entire course of human and angelic history before creating humans and the other beings--aka. Angels and Demons. To deny this fact is to say that the god of Abraham is not all knowing and does not exist outside of time/space. There can be no middle ground with this idea. Either god knows everything or he does not.
So, where do we go from here?
First, we must now see that god created Lucifer knowing that his creation would turn on him and be defeated. Lucifer was also aware that god knew this before he created him but challenged him anyway. Thus, god created Lucifer knowing he was creating "the devil" and hell.
Secondly, god created the devil and hell knowing that he would create humans who would not listen to him and he would be sending them to hell. Thus, before god created Adam and Eve... before the fall of man... god was aware he would be sending most of the creatures he created to suffer eternally.
Therefore, if god is all knowing--- he created the majority of the beings knowing that the entire existence would be spent suffering eternal torture.
Is this a loving god?
But the idea that god is all knowing has another destructive effect on Hebrew story of creation. Anyone who has actually read the story, knows that god was not only not paying attention while the snake tricked Eve, he was surprised to find out about it.
Genesis Chapter 3, Verse 9 (King James)
"And the LORD God called unto Adam, and said unto him, Where art thou?"
Therefore, the story as we know it either cannot be the exact word of god or god is not all knowing. There cannot be any middle ground on this thought.
The implications of this line of thought are infinite--all significantly damaging to the philosophy of an omnipotent, personal god. But these very few examples are intended to stimulate thought and prove nothing by themselves. After all, religion is characterized by faith with lack of evidence -- it cannot be proved or disproved by anything.
