1 Corinthians 9:26

The apostle proposeth his own example. As it is observed in country work, he that only bids his servants do work, and puts not his own hand to it, or at least doth not attend and overlook them in their work, hath little done: so it is as observable in spiritual work, that a minister of the gospel, who only, in the pulpit, dictates duty to others, but, out of it, doth nothing of himself, seldom doth any good by his preaching. People not naturally inclined to any spiritual duty, have the old proverb: Physician, cure thyself, at their tongue's end, and are hard to believe that teacher, who doth not in some measure live up to his own doctrine. Therefore, saith the apostle: I run; I am in the same race with you, and running to the same mark and for the same prize. I give you no other counsel than I myself take; I endeavour so to live, so in all things to behave myself, as I may not be at uncertainties whether I please God by my actions, or shall get to heaven, yea or not. I am a fellow soldier with you, fighting against sin; I make it my great business, not so to fight, so to resist sin, as if I did beat the air; that is, get no more fruit, profit, or advantage by it, than if I threw stones against the wind, or with a staff did beat the air. It is not every running, or every fighting, that will bring a man to heaven; it must be a running with all our might, and continuing our motion till we come to the end of our race; a fighting with all our might, and that against all sin.
