The Fuller.

 
THE fuller rendered garments clean and white, and in his work he used nitre or soap, and he trod upon the garments or beat them. Thus were impurities removed and stains cleansed away. Allusion is made to this when the Lord God says to sinful Israel, stained and defiled by sin, “though thou wash thee with nitre, and take thee much soap, yet thine iniquity is marked before Me” (Jer. 2:2222For though thou wash thee with nitre, and take thee much soap, yet thine iniquity is marked before me, saith the Lord God. (Jeremiah 2:22)), for the efforts of man cannot remove the stains of sins or efface the defilement of evil from him. No art or effort of the fuller can render the soul white in the sight of God.
When the Lord shall come to the earth again He will, says the prophet, be “like fullers’ soap” (Mal. 3:22But 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: (Malachi 3:2)), for He will Himself cleanse and fit His ancient people for His presence.
On the mount of transfiguration Jesus’ “raiment became shining, exceeding white as snow; so as no fuller on earth can white them.” (Mark 9:33And his raiment became shining, exceeding white as snow; so as no fuller on earth can white them. (Mark 9:3).)
He was seen for a moment arrayed in heavenly brightness and regality; for a moment the kingdom of God was beheld in power. No human hand gave that whiteness to His robes―snow-white, and heavenly in splendor; the glory and the purity they declared were beyond all human power to produce.
“Who may abide the day of His coming? and who shall stand when He appeareth?” (Mal. 3:22But 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: (Malachi 3:2)), for holiness becomes God’s house forever. How shall the stains of sin be taken away, and man be rendered fit for the light. Who shall stand arrayed in white robes in the radiant courts of glory? No earthly whiteness will avail for heaven. Only such as are washed in the blood of the Lamb is the answer, and His blood washes whiter than snow. In that day the Lord’s people shall walk with Him in white—in heavenly brightness and in garments exceeding white as snow.
“These are they which came out of (the) great tribulation, and have washed their robes, and made them white in the blood of the Lamb.” (Rev. 7:44And I heard the number of them which were sealed: and there were sealed an hundred and forty and four thousand of all the tribes of the children of Israel. (Revelation 7:4).)
