Satan — Who He Is and What He Does

Satan is the most prominent personal adversary in Scripture. Discover what the Bible actually teaches about who Satan is, his origin, his limitations, and his strategies against believers.

📖 Key Scriptures

1 Peter 5:8-9, John 8:44, Colossians 2:15

Neither Dismissed Nor Obsessed Over

Two equal and opposite errors characterise how Christians think about Satan. The first is dismissal — treating Satan as a mythological figure, a symbol for evil, or an embarrassing relic of pre-scientific worldview. The second is obsession — an unhealthy preoccupation with demonic activity that sees Satan behind every difficulty and attributes more power to him than Scripture warrants.

The New Testament charts a clear middle path: Satan is real, powerful, and actively hostile — and he is a defeated, limited, creaturely enemy operating under God's sovereign permission.

What the Bible Teaches About Satan

His origin. Satan was not created evil — he was a high-ranking angelic being who fell through pride. Isaiah 14:12-15 and Ezekiel 28:12-17 are often understood as describing his fall: a creature of great beauty and privilege who chose to exalt himself against God. Jesus said "I saw Satan fall like lightning from heaven." (Luke 10:18).

His names. Each name reveals an aspect of his character and activity:

  • *Satan* — "adversary" or "accuser" (Job 1:6, Revelation 12:10)
  • *Devil* (*diabolos*) — "slanderer" (Matthew 4:1)
  • *The Tempter* (Matthew 4:3)
  • *The father of lies* (John 8:44)
  • *The god of this age* (2 Corinthians 4:4)
  • *The ruler of this world* (John 12:31)
  • *A roaring lion* (1 Peter 5:8)

His strategies. Satan works primarily through deception — "there is no truth in him... he is a liar and the father of lies." (John 8:44). He masquerades as an angel of light (2 Corinthians 11:14). He accuses believers before God (Revelation 12:10). He tempts toward sin (1 Thessalonians 3:5). He blinds unbelievers to the gospel (2 Corinthians 4:4).

His limitations. Satan is not omniscient, omnipresent, or omnipotent. He is a creature — powerful, but bounded. He operates only within God's sovereign permission (Job 1:12, Luke 22:31-32). He has been decisively defeated at the cross (Colossians 2:15) and will be finally destroyed (Revelation 20:10).

The Right Response

Peter's instruction: "Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. Resist him, firm in your faith." (1 Peter 5:8-9). Watchful and resistant — not fearful, not fascinated, but alert and standing firm in Christ.
