“The arrogant human heart is the source of the sin concerning wealth, and the arrogant human heart sins this way in the proximity of wealth. Wealth is not the locus of the sin, but the presence of the wealth is the locus of the temptation. Just as a beautiful woman is not the cause of lust, but merely the occasion for it, so also the presence of wealth is not the cause of self-sufficiency. But we see, over and again from Genesis to Revelation, that wealth provides the occasion for the sin of self-sufficiency. As Cotton Mather once put it, ‘Faithfulness begat prosperity, and the daughter devoured the mother.’”
