By the world, then, is meant this course of things which we see carried on by means of human agency, with all its duties and pursuits. It is not necessarily a sinful system; rather it is framed, as I have said, by God Himself, and therefore cannot be otherwise than good. And yet even thus considering it, we are bid not to love the world: even in this sense the world is an enemy of our souls; and for this reason, because the love of it is dangerous to beings circumstanced as we are,—things in themselves good being not good to us sinners. And this state of things which we see, fair and excellent in itself, is very likely (for the very reason that it is seen, and because the spiritual and future world is not seen) to seduce our wayward hearts from our true and eternal good. As the traveller on serious business may be tempted to linger, while he gazes on the beauty of the prospect which opens on his way, so this well-ordered and divinely-governed world, with all its blessings of sense and knowledge, may lead us to neglect those interests which will endure when itself has passed away. In truth, it promises more than it can fulfil. The goods of life and the applause of men have their excellence, and, as far as they go, are really good; but they are short-lived. And hence it is that many pursuits in themselves honest and right, are nevertheless to be engaged in with caution, lest they seduce us; and those perhaps with especial caution, which tend to the well-being of men in this life. The sciences, for instance, of good government, of acquiring wealth, of preventing and relieving want, and the like, are for this reason especially dangerous; for fixing, as they do, our exertions on this world as an end, they go far to persuade us that they have no other end; they accustom us to think too much of success in life and temporal prosperity; nay, they may even teach us to be jealous of religion and its institutions, as if these stood in our way, preventing us from doing so much for the worldly interests of mankind as we might wish.
