What does it mean that our warfare is accomplished?

Isaiah 40:2 proclaims, 'Speak comfort to Jerusalem, and cry out to her that her warfare is accomplished.' This declaration signifies that Christ has fully paid the price for our sins and secured our redemption on the cross. The past tense ‘accomplished’ reassures believers that the struggles of sin and condemnation are overshadowed by Christ's victory. As such, there is no further work required for us to earn our salvation—it is already completed, allowing us to rest in His finished work.
