God created the angel by the name of Lucifer who rebelled against God and fell from his "rank." Unlike humans, angels -- who are created as servants of God -- cannot be redeemed. Their fall is eternal.
You don't address my point. God COULD have prevented this if He really was omnipotent, right? But He chose not to. Knowing that you must agree with me on this, I was trying to point out to you that it is unfair for you to say that my side believes that God created evil and causes evil. We don't.
In fact your entire theory that God doesn't allow those who believe to fall is proven wrong exactly with the fallen angels, for they surely believe in God, yet they fell.
You are using the concept of "belief" completely out of context and you know it, Kosta. "Belief of" and "belief IN and acceptance IN" are completely different concepts. Of course satan believes that God exists. Are you making a serious argument or are you just "pulling my lariat"? :)
He chose to give intelligent creatures freedom and with that freedom the uncertainty of their decision. The uncertainty is only ours because we don't know where our choices lead us. God knows what choices we will (freely) make. Freedom ensures that those who come to God do so on their own free will. Forced "love" is no love, so unless we come to Him on our own, and with His help, we are captives of His will, and therefore not free, but rather forced.
Freedom entails the possibility to sin, but also the possibility to repent. Lucifer chose to sin, and so did Adam and Eve. So do you and so do I. But we also have the freedom to repent. Prodigal son story is an example of that. God lets you live and will take you back if you come to Him on your own and ask Him to take you back.
In your theology, God creates evil for His own purpose -- whatever that might be. Because evil exists, it must be because God wills it to exist, so He is the source and cause of evil as well as of everything else.
As for your acrobatics about the verb "believe" -- Scriptures simply say that those who believe will be saved.
