Great, I love when people ask questions such as this. First, there's a couple points I need to make, for everyone in this thread. Sin is not a concrete object. Sin is just breaking any of God's rules. Next, God did not create Satan as an evil being. He was an angel, the most beautiful of angels. (Isaiah 14:12) He was created with free will. I will explain this in a moment. He was set as a kind of head-angel. He decided that he wanted to be God, but was thrown out of heaven, along with many other angels who sinned along with him. To answer the question, it kind of still has to do with free will, and the character of God. Read this article. If God simply killed the Devil, we would then be afraid of him, and serve him out of fear. God instead wants us to serve him out of love. On the subject of free will, I guess I've already gone through it. God gave us the opportunity to obey or disobey him, and for us to choose to serve Him out of our love and reverence for Him. [/hide] So, God is a cowardly [bleep]? What? How did you get that?
