Satan is a spiritual being who led a heavenly revolt against God and was  subsequently cast down into the earth (Luke 10:18).  His personal name, “Satan,” means “adversary.” This name indicates Satan’s basic  nature: he is the enemy of God, of all God does, and of all God loves.

He is also called “the devil” in the New Testament. The word “devil” means  “false accuser” or “slanderer.” Satan plays this role in Job 1–2 when he attacks  Job’s character.

In Matthew  12:24, the Jews refer to Satan as “Beelzebul,” an epithet derived from  “Baal-Zebub” (“lord of the fly”), a false god of the Philistines in Ekron (2 Kings 1:2-3, 6).

Other titles of  Satan include the tempter (1  Thessalonians 3:5), the wicked one (Matthew  13:19, 38), the  accuser of the brethren (Revelation  12:10), and—three titles that point to Satan’s authority in this world—the  ruler of this world (John 12:31),  the god of this age (2  Corinthians 4:4), and the prince of the power of the air (Ephesians 2:2). Second Corinthians  11:14 says that Satan transforms himself into “an angel of light,” a  description that highlights his capacity and inclination to deceive.

There are a couple of passages which refer to the judgment of earthly kings but  may very well also refer to Satan. The first is Isaiah  14:12-15. This is addressed to the king of Babylon (verse 4), but the  description also seems to fit that of a more powerful being. The name “Lucifer,”  which means “morning star,” is used here to describe someone who sought to  overthrow God’s very throne.

The second passage is Ezekiel 28:11-19,  addressed to the king of Tyre. As in the “Lucifer” passage, this prophecy  contains wording that seems to go beyond the description of a mere mortal. The  king of Tyre is said to be “anointed as a guardian cherub,” but he was laid low  by pride and “expelled” by God Himself.

In addition to providing names  and titles of Satan, the Bible uses various metaphors to reveal the character of  the enemy. Jesus, in the parable of the four soils, likens Satan to the birds  that snatch the seed off the hardened ground (Matthew  13:4, 19). In  another parable, Satan appears as the sower of weeds among the wheat (Matthew 13:25, 28). Satan is analogous to  a wolf in John 10:12 and a roaring lion in 1 Peter 5:8.  In Revelation  12:9, Satan is the “great dragon . . . that serpent of old”—obviously, a  reference to the serpent who deceived Eve (Genesis  3:1).
