_Direct._ V. Be always furnished with those particular truths which may be most useful in this service. Study to do your work (in your degree) as ministers study to do theirs; who are not contented with the habitual furniture of their minds, but they also make particular preparations for their particular work. If you are to go into the field to your labour, you will take those tools with you by which it must be done: so do when you go abroad among any that you may do good to, and be not unfurnished for edifying discourse. _Direct._ VI. Speak most of the greatest things, (the folly of sin, the vanity of the world, the certainty and nearness of death and judgment, the overwhelming weight of eternity, the necessity of holiness, the work of redemption, &c.) and choose not the smaller matters of religion to spend your time upon (unless upon some special reason). Among good men that will not lose their time on vanity, the devil too oft prevaileth, to make them lose it by such religious conference, as is little to edification, that greater matters may be thereby thrust out; such as Paul calleth "Vain janglings, and doting about questions which engender strife, and not godly edifying:" as about their several opinions or parties, or comparing one preacher or person with another, or such things as tend but little to make the hearers more wise, or holy, or heavenly. _Direct._ VII. Suit all your discourse to the quality of your auditors. That which is best in itself, may not be best for every hearer. You must vary both your subject and manner of discourse, 1. According to the variety of men's knowledge: the wise and the foolish must not be spoken to alike. 2. According to the variety of their moral qualities: one may be very pious, and another weak in grace, and another only teachable and tractable, and another wicked and impenitent, and another obstinate and scornful. These must not be talked to with the same manner of discourse. 3. According to the variety of particular sins which they are inclined to; which in some is pride, in some sensuality, lust, or idleness, in some covetousness, and in some an erroneous zeal against the church and cause of Christ. Every wise physician will vary his remedies, not only according to the kind of the disease, but according to its various accidents, and the complexion also of the patient. _Direct._ VIII. Be sure to do most where you have most authority and obligation. He that will neglect and slight his family, relations, children, and servants, who are under him, and always with him, and yet be zealous for the conversion of strangers, doth discover much hypocrisy, and showeth, that it is something else than the love of souls, or sense of duty, which carrieth him on.
