Work is the fruitful transformation of the world through human effort and skill, in ways that serve our shared human needs and give glory to God. Work requires wisdom—understanding something about the world, its limitations, and its possibilities. And work requires courage, because even work at its best involves risk and effort, and in a fallen world, work is not often at its best. Work also requires wisdom and courage because we always work together with others, and other human beings are never easy to understand or work with.
