The Bible describes the devil, our spiritual enemy, in a number of ways. The most well-known is the serpent, who was cursed by God to crawl on his belly for deceiving Eve. What was he like before the curse? Video, 5:44
The Bible makes it clear from Genesis to Revelation that the primary tool of the devil is deception. As Dixon says: the devil is a liar, says he can give you everything that you desire, everything you want but you'd be playing with the fire... so don't believe the lie. It comes at a price.
