Why is Christ's finished work significant for believers?

The significance of Christ's finished work cannot be overstated. It represents the fulfillment of God's redemptive plan, whereby Christ, through His life, death, and resurrection, secured the salvation of His people. The assertion 'It is finished' denotes that the requisite atonement for sin was fully satisfied, meaning there is nothing that we can add or subtract from it. This completed work offers believers a profound assurance of their standing before God, allowing us to rest in His grace rather than in our own merits or works. It underscores the truth that salvation is by grace alone through faith alone, singularly grounded in the person and work of Jesus Christ.
