Who Is Satan According to the Bible?

Satan (meaning 'adversary') was originally a magnificent angel who fell through pride. Isaiah 14:12-15 and Ezekiel 28:12-17 are often interpreted as describing his fall: he was 'full of wisdom, and perfect in beauty' but said in his heart, 'I will be like the most High.' He appeared in Eden as the serpent, tempting Eve to disobey God (Genesis 3). He accused Job before God's throne (Job 1-2). He tempted Jesus in the wilderness (Matthew 4:1-11). Jesus called him 'a murderer from the beginning' and 'the father of lies' (John 8:44). Peter warns that he prowls 'as a roaring lion, seeking whom he may devour' (1 Peter 5:8). Paul calls him 'the god of this world' who blinds unbelievers (2 Corinthians 4:4). Yet Satan is not God's equal — he is a created being operating under divine permission. Jesus said, 'I beheld Satan as lightning fall from heaven' (Luke 10:18). Revelation 20:10 foretells his final doom in the lake of fire. He is powerful but already defeated at the cross (Colossians 2:15).
