Victory, conquest, triumph. Nikē in the NT describes the believer's overcoming through faith. The related verb nikaō (to conquer) appears frequently in Revelation's letters to the churches, promising rewards to 'the one who overcomes.'
The Christian's victory is not achieved by human strength but by faith: 'This is the victory that has overcome the world — our faith' (1 John 5:4). In Revelation, the Lamb who was slain is the ultimate nikōn (conqueror) — He conquers through sacrifice, not violence. Paul's triumph cry: 'Thanks be to God, who gives us the victory through our Lord Jesus Christ' (1 Corinthians 15:57). The victory is already won; believers enter into it by faith.
