What is the significance of the statement 'It is finished' in relation to peace?

'It is finished' encapsulates the essence of Christ's atonement, marking the end of the sacrificial system and the fulfillment of God's redemptive plan. This statement, found in John 19:30, assures believers that every requirement of the law was satisfied through Christ's sacrifice. Consequently, believers no longer need to strive for salvation or live in uncertainty regarding their standing before God. This assurance results in profound peace, allowing them to rest in the knowledge that their sins are fully atoned for and they are accepted in the beloved, eliminating confusion surrounding their salvation.
