Refiners fire fullers soap

 Malachi 3:2-3

But who may abide the day of HIS coming ? and who shall stand when HE appeareth ? for HE is like a refiners fire, and like a fullers soap . 

And HE shall sit as a refiners and purifier of silver : and HE shall purify the sons of Levi , and purge them as gold and silver , that they may offer unto the LORD and offering in righteousness . 

tsaraph is the Hebrew word used for refiners . it means to smelt , refine, purge away, try , melt.

compared to the process of purifying precious metals like silver or gold. testing is proof of value 

the fire that burns away who we were the fire that refines who we are and the fire preparing us for who we are becoming - total transformation 

trials and tests are not punishment they are purification .heat and pressure cause the impurities in gold to surface impurities that weren't previously seen impurities that were well hid in gold . fiery trials cause any impurities in us to surface and its for purification that such things must not be hid but come to surface 

the fire of GOD frees us from bondages burns away the dross 

silver refiners heat the metal until all the impurities rise to the surface the dross the contamination everything that weakened the silver. they they scrape it off and repeat the process again and again until they see their own reflection in the silver and that is when they know it is pure. likewise the process is with us in the hands of our FATHER until the LORD sees HIS pure image and reflection in us .

GOD is going to burn away everything in us that cannot stand before HIM.

testing for purity refining fire to purge away the dross

Isaiah 1:25 

I will turn MY hand upon thee, and purely purge away thy dross, and take away thy tin. 

Dross in Hebrew means the waste materials, impurities,

tin in Hebrew means mud miry clay 

Zechariah 13:9 

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. 

Here HE says through the fire why ? the purpose to refine them as silver is refined. so again the Hebrew word is Tsaraph and means to test through fire to melt down to purify to sanctify 

silver refiners heat the metal until all the impurities rise to the surface all the dross all the waste all the contaminants that weaken it . then they scrape it off and repeat this process again and again until they see their own reflection in the silver that is when they know it is pure when it reflects their image looking into it and upon it

the Hebrew word for try used in Zechariah 13:9 the Hebrew word for try is bachan which means to test , try , examine, prove . it implies a thorough examination to determine quality or character such as testing gold. 

Psalm 66:10

For thou, O GOD, hast proved us : thou hast tried us as silver is tried .

Psalm 12:6 

The words of the LORD are pure words : as silver is tried in a furnace of earth , purified seven times.
