Heat purifies gold; that is, gold is made valuable when the impurities are removed.
How well the gold is purified, however, involves a careful process. A jeweler scratches the gold with a needle and conducts a series of tests with an acidic solution. When done right, the jeweler can distinguish a 2 karat diamond from a 14 karat diamond.
“It is a sad reality that fakes exist in the gold market, particularly because gold jewelry has virtually no regulation or oversight…To protect your investment against forgeries and to make sure you are getting the gold you pay for, it is important to test the purity of the gold” (ehow.com).
Purity, spiritually speaking, is commonly defined as the removal of sin in our lives. Removing sin, hence to be made pure, is a process by the heat of suffering, when life’s tragedies hit the hardest. God finds the most value in his children where their sinful impurities of character are removed.
The Lord is a jeweler who tests the quality of his diamonds. Unfortunately, there are fakes in the market, and I don’t know about you, but I don’t want to defraud my Master. The scratching, prodding, and acid bath may be painful, but I know it will always be done right.
