Why is the death of Christ significant for Christians?

The death of Christ on the cross holds paramount significance for Christians as it serves as the ultimate sacrifice for sin, providing the means by which believers are reconciled to God. According to Hebrews 10:10, we are sanctified through the offering of Jesus Christ once for all. This sacrificial act not only pays the penalty for our sins but also fulfills the righteousness required by God's law. By His death, Christ defeated sin and death, allowing us to come into a new relationship with God through faith in Him. This assurance of salvation and eternal life is central to the Christian faith, as He rose again, guaranteeing our own resurrection and life in Him.
