From one of my favorite books, A Practical View of Christianity, by one of my favorite people, William Wilberforce:
[I]f, when summoned to give an account of our stewardship, we shall be called upon to answer for the use which we have made of our bodily organs, and of the means of relieving the wants and necessities of our fellow-creatures; how much more for the exercise of the nobler and more exalted faculties of our nature, of invention, and judgment, and memory, and for our employment of all the instruments and opportunities of diligent application, and serious reflection, and honest decision. And to what subject might we in all reason be expected to apply more earnestly, than to that wherein our eternal interests are at issue? When God has of his goodness vouchsafed [deigned] to grant us such abundant means of instruction in that which we are most concerned to know, how great must be the guilt, and how awful the punishment of voluntary ignorance!
And why, it may be asked, are we in this pursuit alone to expect knowledge without inquiry, and success without endeavor? The whole analogy of nature inculcates on us a different lesson, and our own judgments in matters of temporal interest and worldly policy confirm the truth of her suggestions. Bountiful as is the hand of Providence, its gifts are not so bestowed as to seduce us into indolence, but to rouse us to exertion; and no one expects to attain to the height of learning, or arts, or power, or wealth, or military glory, without vigorous resolution, and strenuous diligence, and steady perseverance. Yet we expect to be Christians without labor, study, or inquiry.
This is the more preposterous, because Christianity, being a revelation from God, and not the invention of man, discovering to us new relations, with their correspondent duties; containing also doctrines, and motives, and practical principles, and rules, peculiar to itself, and almost as new in their nature as supreme in their excellence, we cannot reasonably expect to become proficients in it by the accidental intercourses of life, as one might learn insensibly the maxims of worldly policy, or a scheme of mere morals [emphasis and paragraphs added].
