In 3 Nephi 24:3 says "And he shall sit as a refiner and purifier of silver; and he shall apurify the bsons of Levi, and purge them as gold and silver, that they may coffer unto the Lord an offering in righteousness."
I do believe that this is refering to how Christ purifes us all. The interesting thing is that He compares us to silver. I don't know if this is true, but I heard that when you refine silver you know that it is pure when you can look in the silver and see your reflection. Christ knows we are pure when He can look at us and we have His countanance apon us. How cool is that!
