You may have a whole pocket full of bank notes, but they may not be able to buy you a loaf of bread. If you have the gold of heaven, however, that value will never change. Silver is precious because it has a thousand different uses. The Bible too has a thousand different uses. God's words are useful in so many ways.
Silver is used as ornaments to adorn the body.
These precious words too ought to be our ornaments. We ought to wear them as frontlets between our eyes. These are precious to our souls. The words of God are permanent and they are preserved. The hot fires of this earth have not destroyed His words.
