Why is Christ's role as a refiner important for Christians?

Malachi 3:3 describes Christ as a refiner and purifier, indicating that He plays a vital role in cleansing believers from sin and instilling them with faith. This refining process involves employing various trials in believers' lives, which serve to remove dross—the impurities in their faith. As stated in 1 Peter 1:6-7, the trial of faith is more precious than gold, as it leads to praise, honor, and glory at the revelation of Jesus Christ. Through these trials, believers are drawn to depend wholly on Christ and recognize Him as their source of righteousness and strength.
