Who is Satan? Why is he allowed to exist? What do we know about him?
I understand at one time Satan was an angel in Heaven, the most beautiful. I have often wondered where his sin derived from to want to "take over". As I understand it, he was the one to start "tempting" to cause Eve to sin, but what caused his sin to become what it led to?
Please explain "Loose the four angels which are bound in the great river Euphrates. Revelation 9:14
