He will sit as a refiner and purifier of silver; He will purify the sons of Levi, and purge them as gold and silver, that they may offer to the Lord an offering in righteousness.
Malachi 3:3
The quality of our worship is not based on our activities but on our character. Churches can mistakenly assume that the better the music, the more impressive the building, and the more eloquent the preaching, the more worshipful the experience will be. Genuine worship, however, originates from within our hearts. If our relationship with God is not healthy, all these things are nothing more than religious pageantry. The Levites were the worship leaders of their day. Their task was to offer sacrifices on behalf of the people. God declared that before they could worship Him in righteousness, He would first refine them with His refiner’s fire, purging them of any impurities.
