Why is forgiveness through Jesus important for Christians?

Forgiveness through Jesus is paramount for Christians because it represents the core of the gospel—the justifying work of Christ for sinners. Paul articulates in Acts 13:39, 'And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.' This indicates that through faith in Jesus, believers are declared righteous before God, freed from the guilt of sin. This is vital because it underlines that our relationship with God is based on Christ's completed work and not on our moral or religious efforts, which are incapable of achieving justification. Understanding this truth fosters a deeper appreciation for grace and the assurance of salvation.
