Even though the Scriptures tell us little about Satan’s origin, they do inform us that he is a fallen angel of considerable power. The New Testament describes him as a “great enemy” who “prowls around like a roaring lion, looking for someone to devour.” Jesus Himself said that Satan is such a force to be reckoned with that He is the only one strong enough to conquer him.
Jesus would go on to refer to Satan as the “ruler of this world.” Paul called him the “god of this age.” He also portrayed him as the head of a great, highly organized “army” of evil spirit beings. He is a cunning liar, capable of seducing Adam and Eve by disguising himself as an “angel of light.” The book of Revelation says that his powers of deception are so potent that he is able to lead the whole world astray.
While Satan is portrayed in the Bible as powerful, dangerous, and an adversary to be taken seriously, he shouldn’t be considered in any way equal to God. He is a creature with creaturely limitations. His power is nothing in comparison with that of the Creator of heaven and earth. And according to James 4:7, because of the power God gives to His children, if we submit to Him and resist the devil, Satan will flee from us. Although subtle and cunning, the devil is an already defeated foe who will continue to resist God furiously until the time that he will be sealed in hell forever.
