Why is it significant that Jesus' suffering has ended?

The end of Jesus' suffering is significant because it represents the completion of His earthly mission to bear the sins of humanity. Isaiah 53 portrays Him as a man of sorrows, acquainted with grief, showing that He endured immense pain and suffering as our substitute. Upon declaring 'It is finished,' Jesus affirmed that all of His sufferings were concluded, and justice was satisfied. This is crucial for believers as it assures us that Christ has dealt with our sin and its consequences. His triumph over suffering guarantees eternal life and the promise that believers will not experience separation from God due to sin. As our High Priest, He now intercedes for us without further suffering.
