He will sit as a refiner and purifier of silver; he will purify the Levites and refine them like gold and silver. Then the LORD will have men who will bring offerings in righteousness (Malachi 3:3).
As God refines us, impurities emerge. This gives us the opportunity to bring those things to Christ. Within the purification process, it is important to remember that God is overseeing the whole process. He knows what we can take. What a wonderful promise, He will not test us above our ability. With every temptation, He will also provide a root for escape!
