Today silver and gold are considered archaic forms of money, given the modern trend toward abstract paper money and credit instruments. It would be wise to review some of the reasons that God's Word declares that gold and silver are true wealth and the benefits they could offer Christians at the end of the 20th century. Gold is good. Gold is tested by fire. Notice gold and silver are simply purified by fire, but wood, hay, and stubble are consumed and loss if suffered.
Gold is a sign of power and blessing.
Throughout history the ruling class has always sought to own gold and silver, because they represent purity and longevity. Gold and silver are precious because they are scarce, they cannot be counterfeited by man. God commanded that the tabernacle in the OT and the New Jerusalem in the NT were to be built of gold, not paper. This cannot be said of man's counterfeit credit instruments which are contrary to God's commandment that we use a just weight and measure in our transactions. In conclusion, silver and gold are good, pure, and long lasting froms of value originating and belong to God.
