It is a matter of very great importance, what teachers you choose, in order to your salvation.[70] In this the free grace of God much differenceth some from others: for, as poor heathens and infidels have none that know more, than what the book of nature teacheth (if so much); so in the several nations of christians, it is hard for the people to have any, but such as the sword of the magistrate forceth on them, or the stream of their country's custom recommendeth to them. And it is a wonder, if pure truth and holiness be countenanced by either of these. But, when and where his mercy pleaseth, God sendeth wise and holy teachers, with compassion and diligence to seek the saving of men's souls; so that none but the malignant and obstinate are deprived of their help.
Ambitious, proud, covetous, licentious, ungodly men, are not to be chosen for your teachers, if you have your choice. In a nation where true religion is in credit, and hath the magistrate's countenance, or the major vote, some graceless men may join with better, in preaching and defending the purity of doctrine and holiness of life: and they may be very serviceable to the church herein; especially in expounding and disputing for the truth. But even there, more experienced, spiritual teachers are much more desirable: they will speak most feelingly, who feel what they speak; and they are fittest to bring others to faith and love, who believe, and love God and holiness themselves. They that have life, will speak more lively than the dead. And in most places of the world, the ungodliness of such teachers makes them enemies to the truth which is according to godliness: their natures are at enmity to the life and power of the doctrine which they should preach: and they will do their worst to corrupt the magistrates, and make them of their mind: and, if they can but get the sword to favour them, they are, usually, the cruellest persecutors of the sincere. As it is notorious among the papists, that the baits of power, and honour, and wealth, have so vitiated the body of their clergy, that they conspire to uphold a worldly government and religion; and, in express contradiction to sense and reason, and to antiquity, and the judgment of the church, and to the holy Scriptures, they captivate the ignorant and sensual to their tyranny and false worship, and use the seduced magistrates and multitude, to the persecuting of those that will not follow them to sin and to perdition. Take heed of proud and worldly guides.
And yet it is not every one that pretendeth piety and zeal, that is to be heard, or taken for a teacher. But, 1. Such as preach, ordinarily, the substantial truths which all christians are agreed in. 2. Such as make it the drift of their preaching, to raise your souls to the love of God, and to a holy, heavenly life, and are zealous against confessed sins. 3. Such as contradict not the essential truths, by errors of their own; nor the doctrine of godliness, by wicked, malicious applications. 4. Such as drive not on any ambitious, tyrannical designs of their own, but deny themselves, and aim at your salvation. 5. Such as are not too hot in proselyting you to any singular opinion of their own: it being the prediction of Paul to the Ephesians, Acts xx. 30, "Of your ownselves shall men arise, speaking perverse things, to draw away disciples after them." 6. Such as are judicious with holy zeal, and zealous with judgment. 7. Such as are of experience in the things of God, and not young beginners, or novices in religion. 8. Such as bear reference to the judgments of the generality of wise and godly men, and are tender of the unity of the church; and not such as would draw you into a sect or party, to the contempt of other christians; no, not to a party that hath the favour of rulers and the people, to promote them. 9. Such as are gentle, peaceable, and charitable; and not such as burn with hellish malice against their brethren, nor with an ungodly, or cruel, consuming zeal. 10. Such as live not sensually and wickedly, contrary to the doctrine which they preach; but show by their lives, that they believe what they say, and feel the power of the truths which they preach.
