What does it mean that someone who has suffered in the flesh has ceased from sin?

The statement that he who has suffered in the flesh has ceased from sin (1 Peter 4:1) does not imply a complete absence of sin in a believer's life, but rather speaks to the transformative power of Christ's suffering. This affirms that through Christ's atonement, believers are liberated from the guilt and penalty of sin. By identifying with Christ's suffering, they find themselves in a new relationship with sin—no longer its slaves. Instead, they are empowered by the Holy Spirit to resist sin, and while they continue to struggle with their sinful nature, they are assured of God's grace and forgiveness when they repent. This passage highlights the believer's continual battle with sin while also emphasizing the hope of eventual complete freedom in glory.
