Charles H. Spurgeon on Psalms 67:6

Then shall the earth yield her increase. An increase of wealth is but the natural result of increased piety and intelligence. There are certain qualities essential to temporal prosperity. These are industry, economy, moderation; and such are the qualities begotten of godliness. . . . Nor is it an unreasonable expectation that our globe should, under the reign of righteousness, yield all those temporal advantages of which it is capable. Science, favoured by piety, may greatly add to the earth's fruitfulness; and mechanical genius may still farther abbreviate human toil, and increase human comforts. The great inventions and discoveries of science, by which toil is lessened and comfort enhanced, are all the product of Christian minds... Can we, then, doubt that in the era to which we look forward, labour shall cease to be a burden? Can we believe that the life of the labouring classes is to continue to be all but a ceaseless round of toil and vexation —every hand stretched out to procure something that is needed, or to ward off something that is feared? Scripture predicts the mitigation of the curse; and, in the discoveries of science, and the inventions of mechanics, we see the means by which the prediction is to be accomplished. This consummation may still be in the distant future; but if we do not grudge the oak years for its growth, the glory to be revealed is surely worthy of a process as gradual. William Reid, in "Things to Come Practically Considered," 1871.
