Twenty-four-karat gold is nearly 100 percent gold with few impurities. But that percentage is difficult to achieve. Refiners most commonly use one of two methods for the purification process. The Miller process is the quickest and least expensive, but the resulting gold is only about 99.95 percent pure. The Wohlwill process takes a little more time and costs more, but the gold produced is 99.99 percent pure.
In Bible times, refiners used fire as a gold purifier. Fire caused impurities to rise to the surface for easier removal. In his first letter to believers in Jesus throughout Asia Minor (northern Turkey), the apostle Peter used the gold-refining process as a metaphor for the way trials work in the life of a believer. At that time, many believers were being persecuted by the Romans for their faith in Christ. Peter knew what that was like firsthand. But persecution, Peter explained, brings out the "genuineness of [our] faith" (1 Peter 1:7).
Perhaps you feel like you're in a refiner's fire-feeling the heat of setbacks, illness, or other challenges. But hardship is often the process by which God purifies the gold of our faith. In our pain we might beg God to quickly end the process, but He knows what's best for us, even when life hurts. Keep connected to the Savior, seeking His comfort and peace.
