“And He shall sit as a refiner and purifier of silver: and He shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the Lord an offering in righteousness. . . .” This is the process, the refining, purifying process, which is to be carried on by the Lord of hosts. The work is most trying to the soul, but it is only through this process that the rubbish and defiling impurities can be removed. Our trials are all necessary to bring us close to our heavenly Father, in obedience to His will, that we may offer to the Lord an offering in righteousness.
