Satan preys on people who let their minds go free with whatever thoughts they deem acceptable. God is a God of order, not chaos. God shows us through the Bible that we are unable to control our selfishness without His help. Selfishness (worship of self) is the root of evil and leads to destruction of not only the selfish, but those who follow them. Submission to God, who created you, is the means of living life to its fullest and eternal salvation.
