At the heart of our public morality is the idea that he who gives generously is most virtuous and morally praiseworthy; that there is no greater citizen than she who sacrifices; and that there is no greater measure of worth than contribution. These are values we can be proud of. After all, there is no moral system or religion on earth where the guiding ethic is grab more for yourself.

Our commitment should be to leave our environment in better shape than when we found it, our nation's fiscal house in better order, our public infrastructure in better repair, and our people better educated and healthier. To indulge in immediate gratification and exploitation is an insult to previous generations, who sacrificed for us, and thievery from the next generation, who depend on our virtue.

'The Purpose-Driven Life' is not just a mega-bestselling work of Christian faith; it is the thing that every voter, secular or not, yearns for.

Honest people know that the road to success and virtue always involves shared sacrifice, hard work, and gratification postponed. Telling people otherwise isn't leadership, it is pandering.

True patriots believe that we should measure a citizen's worth by contribution to country and community, not by wealth or power-that those whom America has benefited most should contribute in proportion to their good fortune-and that serving others should be esteemed more highly than serving self.

Conservatives forget that citizenship is more than a thing to withhold from immigrants. Progressives forget it's more than a set of rights.

What does purpose mean? It means the deepest desire for our short lives to mean something. . . . To speak a language of purpose is to return to first principles and to be able to answer, in plain English, the plain questions of Why? Why should we chip in to help someone else? Why should we defer gratification? Why should we care about the long term? Why should we trust anyone who seems to be limiting our ability to do what we want?
