Read Proverbs 25:4  Our verse talks about refining silver.  Many years ago, quarters used to be made of silver, but now they are made of cheaper metals.  When I was a young man and in college, I worked at an iron foundry in Chattanooga.  Iron is much cheaper that silver, but melting the both of them is the same process.  The iron melts at about 2800 degrees and silver at about 1800 degrees.  But iron and silver usually have impurities in them.  When someone wants to make a silver necklace, they must use silver that is pure.  If the silver isn't pure, when they hammer it down into the thin wire needed to make the links in the necklace, the silver wire will break.  It breaks because it has impurities in it.  So before the silversmith makes the silver wire he must heat the silver until it melts. When the silver is a hot liquid, the impurities will float to the top, and the silversmith can skim off the dross from off the top, leaving the pure silver.  The more times that the silversmith melts the silver, the more of the impurities he can get out, and the more pure the silver becomes.  When all of the impurities are out of the silver, then the silversmith can make a beautiful necklace that will be strong and beautiful.  When God takes away our sins, we are a beautiful trophy for Him.  I want God to be proud of me.  And I want God to be proud of you!  Let's let God take away our sins so that we will make Him proud!
