What does Malachi 3:3 mean?
The first accusation brought in Malachi was targeted at the priesthood, for offering impure sacrifices (Malachi 1:6–8). As a result, God threatened to remove impurities from His sanctuary in the same way that priests discarded animal wastes (Malachi 2:3). Here, the same purification is in mind. The priesthood will be "refined."A "refiner's fire" is the process used to remove impurities from precious metals. Since the heat required to melt silver and gold is enough to destroy other materials, this is the method used to generate purer alloys. Here, that metaphor is being applied to the priesthood of Israel. The tribe of Levi was charged with caring for the temple, and only Levites could be priests. Rather than abandon them (Malachi 1:2–5), or destroy them (Malachi 3:6), God plans to refine them. Of course, this means passing through the fire.
Earlier, it was said that God would prefer no sacrifice at all, as opposed to offerings which were inappropriate and indifferent (Malachi 1:10). Part of the purpose of His refining is to restore the worship of His people to something worth accepting (Malachi 1:11). While this may start with the priests, the people also have impure behaviors which need to be purged (Malachi 2:11–13).
Malachi 2:17—3:6 presents a dangerous accusation from Israel against God, and His sobering response. Israel accuses God of letting the wicked prosper and for not enacting enough justice in the world. God's reply reminds Israel, and us, that the first sin we need to be aware of is our own. God promises to send a messenger, preparing the way for Him. God also predicts the day when He will ''draw near'' for judgment. This uses metaphors including fire and powerful cleaning substances. In short, judgment is coming—to everyone.
The final message, completed in chapter 4, is an appeal for God's chosen people to return. God would prefer to see them redeemed, than to be destroyed, when the end finally comes. This passage includes God's promise to send a messenger heralding the Messiah. And, that the Promised One will someday rule and conquer the wicked. In the meantime, Israel must stop ''robbing'' Him by withholding His tithes and offerings. Only God's unchanging nature has kept Israel from destruction. At the same time, God will remember those who have been faithful during these faithless times.
