1. The devil sinned in his heart by having a desire to be like God and because of that was cast out of Heaven, and we are told about it in Isa.14:12-14. 2. Now on the earth he is an accuser of the brethern, Job ch. 1 and 2 along with other fallen beings. 3. In Gen. 3. the devil approached Eve and tempeted her to question the authorship the accuracy and the acceptability of Gods Word. 4. The devil also in Mat.4 tried to temp the Son of God to sin. Many other places in the Bible I believe we see satan working instead of sending his "helpers" the other fallen beings that fell when he did. 5. The devil will be bound for 1000 years, Rev.20:1-3, and then in vs.7 we see him loosed for a short time to deceive the nations and will be defeated. Now, What will be his end and what special treatment does he get or what extra responsibility does satan have yet to fulfill? We find that answer in Rev.20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever. There is absolutely NO Scripture in the entire Bible to tell us our sins are placed on satan! satan has or never had anything to do with salvation, Redemption, the atonement of Christ or anything else pertaining to our eternal Salvation. The devil will pay for sins all right.....his! Just like a person will who rejects Christ.
