Satan in Isaiah 14:12 - 15 was cast out from heaven. He and his followers were cast out of heaven and down to hell. Satan's sins are innumerable, but the one that got him throne out of heaven was being envious of God and trying to set himself up higher than God. Satan, the bible says in James 4:4 hates God and everything that he does. Satan is the prince of this world, and anyone who tries to be of the world is of Satan. The devil, because he hates every thing and everyone that is righteous, in Job goes to God to ask if he can try and get Job to sin. The book of Job proves that Satan does indeed have power, but not power greater than God's. Satan is called a "roaring lion, looking for some victim to devour" (but only if you have the right translation of the Bible) in 1 Peter 5 : 8. Satan despite all his power isn't as persistent as some might think. In James 4:7 we are told to resist the devil and he will flee from you.
             The Devil, as hated as he is, was given quite a few nick-names in scripture. In Revalations 12:10 Satan is called the Accuser of the Brethren. This name is rather self-explanatory, he received this not so honorary name by standing in front of God day and night giving him reasons why we aren't saved and why he should receive our souls in Hell. This name is used when Satan is thrown down to earth after the war in heaven in the end times. Satan is referred to as our adversary in I Peter 5:8. This name is used when Peter is warning us of the devil and his tactics. The names Great Dragon, and Deceiver of the whole world are used in Revalations 12:9 which is also talking about the results of the great battle in heaven. He is called the Father of Lies in John 8:44. Jesus used this name to describe the devil while telling some people at the temple that their father is Satan. He is also called a murderer in John 8:44. In 2 Cor. 4:4 Satan is called the god of this world. Pau...
