St. Paul having directed Titus what doctrine to preach, comes now to instruct him what example to lead, in all things show thyself a pattern of good works; as if he had said, In all the good which thou exhortest thy hearers to, be an eminent pattern of it thyself; that they may see that visibly in thy life, which thou pressest upon them by thy preaching. By piety and good works second thy doctrine; there must be a sweet harmony between a minister's doctrine and his conversation; otherwise he pulls down faster than he builds up: an heterodox conversation will carry an orthodox preacher to hell.
He closes this admonition to Titus concerning preaching, with this solemn charge, namely, that his doctrine be sound and profitable, sincere without mixture, grave without levity, sound words that can never be confuted by gainsayers, which must be expected; but happy will you be if they can have nothing justly to charge your doctrine or conversation with.
Learn hence, that the ministers of God have ever had, and must always expect, some that will withstand, oppose, and gainsay them, as long as there is a devil in the world: and so long as the ministers of God endeavour to batter down the walls of his kingdom, he will raise up storms about their ears.
Learn, 2. That it is the duty, and must be the care and endeavour, of all the ministers of God, to oblige themselves to such an exemplary piety of conversation, as may stop the mouth of slander. That the contrary part may be ashamed, having no evil to say against them.
