"suffering is an essential part of what He calls Redemption"

Suffering, according to the New Testament writers, 'produces perseverance' and is necessary so that believers might share in Christ's glory. The apostle Peter believed followers of Jesus should rejoice when they 'participate in the sufferings of Christ'.

One of the tenets of Christianity is that Jesus saved humanity from eternal damnation when he died on the cross and descended into hell. The word Redemption, in historical terms, meant buying a slave's freedom. In a spiritual sense, Jesus paid for humanity's freedom from sin with his own life. As Paul explained to the believers in Corinth, 'You are not your own; you were bought at a price.'
