Charles H. Spurgeon on Psalms 119:72

Thousands of gold and silver. Worldly riches are gotten with labour, kept with care, lost with grief. They are false friends, farthest from us when we have most need of comfort; as all worldlings shall find to be true in the hour of death. For then, as Jonah's gourd was taken from him in a morning, when he had most need of it against the sun; so is it with the comfort of worldlings. It is far otherwise with the word of God; for if we will lay it up in our hearts, as Mary did, the comfort thereof shall sustain us, when all other comfort shall fail us.

This it is that makes us rich unto God, when our souls are storehouses, filled with the treasures of his word. Shall we think it poverty to be scant of gold and silver? "An ideo angelus pauperest, quia non habet jumenta", etc (Chrysostom). Shall we esteem the angels poor, because they have not flocks of cattle? or that S. Peter was poor, because he had not gold nor silver to give unto the cripple? No, he had store of grace, by infinite degrees more excellent than it.

Let the riches of gold be left unto worldlings: these are not current: in Canaan, not accounted of in our heavenly country. If we would be in any estimation there, let us enrich our souls with spiritual graces, which we have in abundance in the mines and treasures of the word of God. William Cowper.
