How do we know that Jesus completed His work?

We find assurance of Jesus completing His work in His own words from John 19:30, where He declares, 'It is finished.' This pronouncement marks the culmination of His mission to atone for the sins of His elect, satisfying the demands of divine justice. Furthermore, the Scripture teaches that He did not simply allow sin and evil to go unpunished, but instead bore the weight of sin on behalf of His people, leading to their reconciliation with God. His victorious sacrifice assures believers that they are fully justified and accepted in Him, emphasizing the completion of God's redemptive plan.
