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.
