Malachi 3:1-4 MSG

1 "Look! I'm sending my messenger on ahead to clear the way for me. Suddenly, out of the blue, the Leader you've been looking for will enter his Temple - yes, the Messenger of the Covenant, the one you've been waiting for. Look! He's on his way!" A Message from the mouth of God-of-the-Angel-Armies.
2 But who will be able to stand up to that coming? Who can survive his appearance? He'll be like white-hot fire from the smelter's furnace. He'll be like the strongest lye soap at the laundry.
3 He'll take his place as a refiner of silver, as a cleanser of dirty clothes. He'll scrub the Levite priests clean, refine them like gold and silver, until they're fit for God, fit to present offerings of righteousness.
4 Then, and only then, will Judah and Jerusalem be fit and pleasing to God, as they used to be in the years long ago.
