What is the opposite of God?

That was a question that was asked yesterday during the sermon by the Sr. Protestant Chaplain at RAF Mildenhall. He tackled issues about the devil. Is the devil real or just a scapegoat was the question asked. He explained that in early Bible times, common medical problems were thought of a demons. Going through the Bible, we read that the devil is real spirit that has control to interfere with our lives. He asked the question about what is opposite of God and the common answer is the devil. Make sense, God is all love and the devil is all evil. He used Star Wars as an example. In Star Wars, there is one force with 2 ends. But that is not right, saying that the devil is the opposite of God is giving the devil the position of a god. This proves that Star Wars is not a good example to relationship of God and the devil. Reading the Bible tells us that the devil was an angel. He was believe he could be god and tried to overtake his creator. So who is the opposite of God and who is the opposite of the devil? There is nothing that is opposite of God because there is not all powerful like God. There is nothing that can destroy what God has created. Jesus is also not opposite him because Jesus is God. Then the opposite of the devil would have be the head archangel maybe Michael. Which makes perfect sense since both are angels. This is all I remember from the sermon, but these were the main parts of the sermon. He used several examples from the Bible to prove his points.
