Why is Jesus' finished work significant for our rest?

The significance of Jesus’ finished work cannot be overstated, as it provides true and lasting rest for believers. When Jesus declared, 'It is finished' (John 19:30), He marked the completion of His atoning sacrifice, which addressed the penalty of sin and restored our relationship with God. This accomplishment means that believers are no longer bound to achieve righteousness through their own efforts. Instead, they are invited to rest in the sufficient work of Christ, understanding that salvation is entirely by grace through faith. This transforms the believer's experience from one of striving to one of assurance and peace, as they rest in the grace provided by the finished work of Christ.
