And as these goods lead us to love the world, so again do they lead us to trust in the world: we not only become worldly-minded, but unbelieving; our wills becoming corrupt, our understandings also become dark, and disliking the truth, we gradually learn to maintain and defend error. St. Paul speaks of those who "having put away a good conscience, concerning faith made shipwreck[3]." Familiarity with this world makes men discontented with the doctrine of the narrow way; they fall into heresies, and attempt to attain salvation on easier terms than those which Christ holds out to us. In a variety of ways this love of the world operates. Men's opinions are imperceptibly formed by their wishes. If, for instance, we see our worldly prospects depend, humanly speaking, upon a certain person, we are led to court him, to honour him, and adopt his views, and trust in an arm of flesh, till we forget the overruling power of God's providence, and the necessity of His blessing, for the building of the house and the keeping of the city. And moreover, these temporal advantages, as they are considered, have a strong tendency to render us self-confident. When a man has been advanced in the world by means of his own industry and skill, when he began poor and ends rich, how apt will he be to pride himself, and confide, in his own contrivances and his own resources! Or when a man feels himself possessed of good abilities; of quickness in entering into a subject, or of powers of argument to discourse readily upon it, or of acuteness to detect fallacies in dispute with little effort, or of a delicate and cultivated taste, so as to separate with precision the correct and beautiful in thought and feeling from the faulty and irregular, how will such an one be tempted to self-complacency and self-approbation! how apt will he be to rely upon himself, to rest contented with himself, to be harsh and impetuous; or supercilious; or to be fastidious, indolent, unpractical; and to despise the pure, self-denying, humble temper of religion, as something irrational, dull, enthusiastic, or needlessly rigorous!
