A Bible study leader was curious about this verse, so the woman called a silversmith and made an appointment to watch him at work.
As she watched the silversmith, he held a piece of silver over the fire and let it heat up. He explained that in refining silver, he needed to hold the silver in the middle of the fire where the flames were hottest to burn away all the impurities.
The woman thought about God sometimes holding us in such a hot spot. She asked the silversmith if it was true that he had to sit there in front of the fire the whole time the silver was being refined.
The man answered that yes . He had to keep his eyes on the silver the entire time it was in the fire. If the silver was left a moment too long in the flames, it would be destroyed.
She then asked, "How do you know when the silver is fully refined?"
He smiled at her and answered, "Oh, that's easy -- when I see my image in it."
If today any of God's children are feeling the heat of the fire, we can remember that God has his eye on us and will keep watching lovingly until He sees His image in us.
We are assured and know that [God being a partner in their labor] all things work together and are [fitting into a plan] for good to and for those who love God and are called according to [His] design and purpose.
For those whom He foreknew [of whom He was aware and loved beforehand], He also destined from the beginning [foreordaining them] to be molded into the image of His Son [and share inwardly His likeness], that He might become the firstborn among many brethren Romans 8:28-29
