Some time ago, a few people met to study the scriptures. While reading the third chapter of Malachi, they came upon a remarkable expression in the third verse: "And He shall sit as a refiner and purifier of silver" (Malachi 3:3).
 
One woman proposed to visit a silversmith and report back to them on what he said about the subject. She went, and without telling the object of her errand, asked the silversmith to tell her about the process of refining silver.

After he had fully described it to her, she asked, "But sir, do you sit while the work of refining is going on?"

"Oh, yes ma'am," replied the silversmith, "I must sit with my eyes steadily fixed on the furnace, for if the time necessary for refining be exceeded in the slightest degree, the silver will be injured."

The lady at once saw the beauty of the expression, "He shall sit as a refiner and purifier of silver." Although God allows His children to endure the furnace; His eye is steadily intent on the work of purifying, and His wisdom and love are both engaged for us. Our trials do come, but He will not let us be tested beyond what we can endure.  

Before she left, the lady asked one final question, "When do you know the process is complete?"

"Why, that is quite simple," replied the silversmith. "When I can see my own image in the silver, the refining process is finished."
