My dear friend A. shared this story with me. I'll share it with you, as it has been a great encouragement to me.
How is silver refined? The silversmith places unpurified silver into a small cauldron and then lowers it into the hottest part of the fire to burn off imperfections and impurities. Knowing that if the silver is burned too long, it will be destroyed, a bystander asked how the silversmith knew when it was time to take the silver out of the fire. He replied, "I stand by the entire time and remove the silver when I can see my reflection."
"He will sit as a refiner and purifier of silver . . ." --Malachi 3:3
