Ezekiel 22:18-22

22:18 “Son of man, the house of Israel has become slag to me. All of them are like bronze, tin, iron, and lead in the furnace; they are the worthless slag of silver. 22:19 Therefore this is what the sovereign Lord says: ‘Because all of you have become slag, look out! – I am about to gather you in the middle of Jerusalem. 22:20 As silver, bronze, iron, lead, and tin are gathered in a furnace so that the fire can melt them, so I will gather you in my anger and in my rage. I will deposit you there and melt you. 22:21 I will gather you and blow on you with the fire of my fury, and you will be melted in it. 22:22 As silver is melted in a furnace, so you will be melted in it, and you will know that I, the Lord, have poured out my anger on you.’”

Malachi 3:2-3

3:2 Who can endure the day of his coming? Who can keep standing when he appears? For he will be like a refiner’s fire, like a launderer’s soap. 3:3 He will act like a refiner and purifier of silver and will cleanse the Levites and refine them like gold and silver. Then they will offer the Lord a proper offering.

Malachi 4:1

Matthew 3:11-12

3:11 “I baptize you with water, for repentance, but the one coming after me is more powerful than I am – I am not worthy to carry his sandals. He will baptize you with the Holy Spirit and fire. 3:12 His winnowing fork is in his hand, and he will clean out his threshing floor and will gather his wheat into the storehouse, but the chaff he will burn up with inextinguishable fire.”

John 16:8-11
