The Importance of Spiritual Conflict in the Bible

Every single human being that has ever existed and will exist is made in the image of who? God, that's right. Every time a demon sees a human being, even a Hitler or a Stalin, they see their enemy. They absolutely hate human beings with an intensity that I cannot preach or explain to you because you are the living embodiment of the one they rebelled against before the beginning of time. But what blows my mind is spiritual conflict begins in Genesis 1, 2 and ends in Revelation 20.
