Therefore I shall think my time not ill spent, if I can persuade most or all of you who hear me, to shew the love you have for your country, by endeavouring, in your several stations, to do all the public good you are able. For I am certainly persuaded, that all our misfortunes arise from no other original cause than that general disregard among us to the public welfare. I therefore undertake to shew you three things. _First_: That there are few people so weak or mean, who have it not sometimes in their power to be useful to the public. _Secondly_: That it is often in the power of the meanest among mankind to do mischief to the public. And, _Lastly_: That all wilful injuries done to the public are very great and aggravated sins in the sight of God. _First_: There are few people so weak or mean, who have it not sometimes in their power to be useful to the public. Solomon tells us of a poor wise man who saved a city by his counsel. It hath often happened that a private soldier, by some unexpected brave attempt, hath been instrumental in obtaining a great victory. How many obscure men have been authors of very useful inventions, whereof the world now reaps the benefit? The very example of honesty and industry in a poor tradesman will sometimes spread through a neighbourhood, when others see how successful he is; and thus so many useful members are gained, for which the whole body of the public is the better. Whoever is blessed with a true public spirit, God will certainly put it into his way to make use of that blessing, for the ends it was given him, by some means or other: And therefore it hath been observed in most ages, that the greatest actions, for the benefit of the commonwealth, have been performed by the wisdom or courage, the contrivance or industry, of particular men, and not of numbers; and that the safety of a kingdom hath often been owing to those hands from whence it was least expected.
