How do we know that Christians are forgiven for Christ's sake?

The assurance of forgiveness for Christians is grounded in the biblical truth that our forgiveness is secured through the sacrificial work of Christ. Ephesians 4:32 explicitly states, 'God, for Christ's sake, hath forgiven you.' This points to the fundamental Christian doctrine that Jesus' death and resurrection provide the basis for our reconciliation with God. When a believer repents and places faith in Christ, that person is forgiven not based on their merit but solely due to Christ's righteousness and atoning sacrifice. This underscores the essence of sovereign grace; it is entirely God's work to forgive, and we receive it through faith, thereby becoming new creations in Him.
