Adams on Psalm 14:1

They are corrupt, they have done abominable works. Sin pleaseth the flesh. Omne simile nutrit simile. Corruption inherent is nourished by the accession of corrupt actions. Judas's covetousness is sweetened with unjust gain. Joab is heartened and hardened with blood. 1 Kings 2:5. Theft is fitted to and fatted in the thievish heart with obvious booties. Pride is fed with the officious compliments of observant grooms. Extortion battens in the usurer's affections by the trolling in of his moneys. Sacrilege thrives in the church-robber by the pleasing distinctions of those sycophant priests, and helped with their not laborious profit. Nature is led, is fed with sense. And when the citadel of the heart is once won, the turret of the understanding will not long hold out. As the suffumigations of the oppressed stomach surge up and cause the headache, or as the thick spumy mists, which vapour up from the dark and foggy earth, do often suffocate the brighter air, and to us more than eclipse the sun, the black and corrupt affections, which ascend out of the nether part of the soul, do no less darken and choke the understanding. Neither can the fire of grace be kept alive at God's altar (man's heart), when the clouds of lust shall rain down such showers of impiety on it. Perit omne judicium, cum res transit ad affectum. Farewell the perspicuity of judgment, when the matter is put to the partiality of affection.

The fool hath said in his heart, There is no God. Popery has not won to itself so great wits as atheism; it is the superfluity of wit that makes atheists. These will not be beaten down with impertinent arguments; disordered hail-shot of Scriptures will never scare them; they must be convinced and beaten by their own weapons. "Hast thou appealed to Caesar? To Caesar thou shalt go." Have they appealed to reason? Let us bring reason to them, that we may bring them to reason. We need not fear the want of weapons in that armoury, but our own ignorance and want of skill to use them. There is enough even in philosophy to convince atheism, and make them confess, "We are foiled with our own weapons;" for with all their wit atheists are fools.

As quoted in Spurgeon's Treasury of David.
