Charles H. Spurgeon on Psalms 62:10

Trust not in oppression, and become not vain in robbery. Wealth ill gotten is the trust only of fools, for the deadly pest lies in it; it is full of canker, it reeks with God's curse. To tread down the poor and silence their cries for justice, is the delight of many a braggart bully, who in his arrogance imagines that he may defy both God and man; but he is warned in these words, and it will be well for him if he takes the warning, for the Judge of all the earth will surely visit upon men the oppression of the innocent, and the robbery of the poor: both of these may be effected legally in the courts of man, but no twistings of the law, no tricks and evasions will avail with the Court of Heaven. If riches increase, set not your heart upon them. If they grow in an honest, providential manner, as the result of industry or commercial success, do not make much account of the circumstance; be not unduly elated, do not fix your love upon your money bags. To bow an immortal spirit to the constant contemplation of fading possessions is extreme folly. Shall those who call the Lord their glory, glory in yellow earth? Shall the image and superscription of Caesar deprive them of communion with him who is the image of the invisible God? As we must not rest in men, so neither must we repose in money. Gain and fame are only so much foam of the sea. All the wealth and honour the whole world can afford would be too slender a thread to bear up the happiness of an immortal soul.
