What does the Bible say about it is finished?

In John 19:30, Jesus proclaims 'It is finished' right before His death, indicating that He has completed the work of salvation through His atoning sacrifice. This declaration emphasizes that the requirements for redemption have been fully met by Christ's obedience and suffering. The Greek term used here captures the essence of completeness, indicating that there is nothing more to be done regarding our redemption. This truth is foundational in understanding the sufficiency of Christ's sacrifice for the elect, who no longer must strive for their own righteousness.
