Has Satan changed since he was cast out of his place of authority?
No. Though Satan was cast out of his place of authority over the kingdom described in Genesis 1:2, Scripture indicates he has never changed. He has not given up; his whole role and reason for existing is to constantly thwart the plan of the sovereign God.
Les explains that Satan was passed out of his place of authority over that beautiful kingdom in Genesis chapter 1, verse 2, yet he has never changed. He has not given up. His whole role and whole reason for existing is to constantly thwart the plan of the sovereign God. For example, as soon as God put that perfect pair in the garden, Satan came in to throw a monkey wrench in the whole caboodle and caused those human parents to sin.
