In the house of the righteous is much treasure, but in the revenues of the wicked is trouble. Proverbs 15:6.
When worldly church-goers hear the word “treasure,” they immediately assume the gold and silver kind are meant; but the person who knows Christ understands that something else is intended—treasures of love, joy, justice, wisdom, and peace. Christian homes, armies, societies and nations are distinguished by such treasures. Often physical treasures follow, too, because people who live well-regulated and honest lives tend to husband natural resources wisely and increase them.
For an example of a home filled with spiritual treasure, one can look to Jonathan and Sarah Edwards. The beauty of their affections and their godly oversight of their children were recorded by contemporaries. Evangelist George Whitefield was so impressed with the love he saw between the pair that he promptly determined to marry himself. His ill-advised union was not so happy.
One of the chief treasures of the Christian is contentment. The revenues that the wicked extract (often by unjust methods) do not bring them much happiness, not least because they constantly crave more and are never satisfied.
Christians enjoy spiritual treasures others can only crave. This is possible because of Jesus, “in whom are hid all the treasures of wisdom and knowledge” (Colossians 2:3) and who “became poor so that we might become rich (2 Corinthians 8:9).” The deposit he has left us is the Holy Spirit, who resides in us, whom Paul likens to those clay pots in which the people of the Middle East stored documents and gems they wished to preserve.
