What happens to Satan in the end?A Scripture-grounded answer about what happens to satan bible

The Bible traces Satan's defeat across a grand narrative arc. Genesis 3:15 — the protoevangelium — promises that the woman's offspring would crush the serpent's head, even as the serpent strikes his heel. This was accomplished at the cross, where Christ 'disarmed the rulers and authorities and put them to open shame, by triumphing over them' (Colossians 2:15). Satan's power is real but limited — a defeated enemy whose sentence has been pronounced but not yet fully executed. Revelation 20 describes the final stages: Satan is bound for a thousand years (whether literally or symbolically), preventing his deception of nations. After this period, he is released for a 'little while,' gathers the nations (symbolically named Gog and Magog, from Ezekiel 38-39), and marches against God's people. The resolution is anticlimactic by design — fire from heaven simply consumes the armies, and Satan is cast into the lake of fire. There is no epic final battle between equals. The God of the Bible is not locked in a dualistic struggle with evil. Satan's defeat is certain, total, and eternal.
