God's Refining Fire

And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The LORD is my God.

~ Zechariah 13:9

But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner's fire, and like fullers' soap:
And he shall sit as a refiner and purifer of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.

~ Malachi 3:2, 3

Behold, I have refined thee, but not with silver; I have chosen thee in the furnace of affliction.

~ Isaiah 48:10

But he knoweth the way that I take: when he hath tried me, I shall come forth as gold.

~ Job 23:10
