The crucible is for silver, and the furnace is for gold,
and the Lord tests hearts. Prov. 17:3
This proverb of Solomon was part of the devotion today for those who use the Treasury of Daily Prayer. It is an amazing thing, and a fearful thing, to ponder.
A crucible is a sort of pot in which you heat up metal or some other chemical compound. You may have used on a chemistry lab. You can use on to purify silver, but gold is a heavier metal. We think of a furnace as something that heats the house, but in this case it refines gold. To purify gold, you have to heat it up to such high temperatures that the impurities, the dross, everything that clings to it that isn’t gold, burns away in the smoke. What remains is purer gold.
The prophets talk about the Lord coming as a refiner’s fire. You put a little chunk of silver over a Bunsen burner, you put a gold ring in a blacksmith’s or a forger’s furnace. The presence of God does to your heart what that furnace does to the gold.
The thing to remember is that God tests hearts because they are precious to Him. He doesn’t do it to cause pain, though the process is painful. Precisely because your heart is precious to Him, He hates the sin that clings to closely. He wants it gone.
When we come into the presence of the Lord, we repent of our sins and submit to the painful process of turning away from them. The sins we love are the hardest to let burn away. Confession of sin that is painless probably isn’t very honest.
Christ redeems us sinners not with gold or silver but with His holy, precious blood. When the Lord tests hearts, He looks for the blood of Christ, more precious than silver, and finds it in the faithful. Therefore we stand in the judgment.
The Judge still hates the dross. The great blessing of ongoing confession/absolution, ongoing Holy Communion, daily remembrance of Baptism, is that is lets you participate, not in your salvation, but in your purifying. It will never happen completely in this life; it will remain a work in progress. But entering into the presence of God and staying there when the knowledge of sin starts to bubble up and the defense mechanisms kick in is a painful but glorious opportunity we all have as members of the Body of Christ.
