What does 'eternal redemption' mean in Hebrews 9:12?

'Eternal redemption' refers to the lasting nature of the salvation accomplished by Christ. In Hebrews 9:12, the term emphasizes that the redemption He secured is not temporary or subject to conditions, but rather a permanent state. This concept reassures believers that once redeemed, they cannot be re-enslaved by sin or loss of salvation. The believer's relationship with God is thus established on the unchangeable work of Christ, ensuring that eternal life is a guaranteed inheritance for all who believe.
