Lutron (G3083) is one of the most theologically loaded words in the New Testament. A lutron was the price paid to free a slave or redeem a prisoner of war. Jesus uses this word only once, but it defines His entire mission: 'The Son of Man came not to be served but to serve, and to give his life as a ransom [lutron] for many' (Matthew 20:28).
The metaphor is commercial but the reality is cosmic: humanity is enslaved to sin and death, and the ransom price for our release is the life of God's own Son. Antilutron (1 Timothy 2:6) โ 'ransom for all' โ makes the substitutionary nature explicit. This is the heart of atonement theology: Jesus is not merely a moral example but the actual ransom payment that sets captives free.
