Christ is also symbolized as a lion, but not as a lion seeking to devour. Lion for Christ is used in the sense of "controlled, majestic power," but for Satan it is the symbol for one who is ruthless, stealthy, powerfully aggressive, bent on defending its turf, and destruction, often working from ambush. There are many similarities with the attributes of the "serpent."
A pride of lions will stalk and attack animals that are larger than they are—including wildebeest and water buffalo weighing thousands of pounds. It is a beautiful, deadly sight to watch lions working together as a team to bring a water buffalo down.
When lions attack, they do so through multiple attacks from every side. Eventually, one lion gets a grip on the throat of the water buffalo and kills it by strangulation. It is a slow and painful death. The water buffalo goes down, and the lions begin eating it before it is dead.
Satan is a lion, roaring, looking for and stalking whom he may devour. Male lions will even eat the young of their own pride to establish their dominance. It does not matter that they are related. If they are hungry, and a little kitten is around . . . one bite and it is gone.
