Why is it important that Christ said 'It is finished'?

'It is finished' is a pivotal phrase uttered by Jesus prior to His death, indicating that the work of redemption has been fully accomplished. J.C. Ryle explains that this declaration encapsulates the fulfillment of the law, the prophecies, and the sacrifices that were necessary for atonement. It reveals that Christ has borne the sins of humanity and satisfied divine justice. This assurance is fundamental for believers, as it means that the debt owed for sin has been fully paid, allowing sinners to find peace and rest in the completed work of Jesus for their salvation. His death marks not the end but a new beginning for those who put their faith in Him.
