And here let me tell you, that it is ignorance to call for particular express Scripture, to require praying in families, as if we thought the general commands did not comprehend this particular, and were not sufficient. God doth in much wisdom leave out of his written law the express determination of some of those circumstantials, or the application of general precepts to some of those subjects, to which common reason and the light of nature sufficeth to determine and apply them. The Scripture giveth us the general, "Pray alway with all manner of prayer in all places," that is, omit no fit advantages and opportunities for prayer. What if God had said no more than this about prayer in Scripture? It seems some men would have said, God hath not required us to pray at all, (when he requireth us to pray always,) because he tells us not when and where, and how oft, and with whom, and in what words, &c. And so they would have concluded God no where bids us pray in secret, nor pray in families, nor pray in assemblies, nor pray with the godly, nor with the wicked, nor pray every day, nor once a week; nor with a book, nor without a book, and therefore not at all. As if the general "Pray on all fit occasions" were nothing. But these men must know that nature also and reason are God's light, and Providence oft determineth of such subjects and adjuncts: and the general law, and these together, do put all out of doubt. What if God telleth you, He that provideth not for his own, especially those of his household, hath denied the faith, and is worse than an infidel, and do not tell you either who are your families, and who not, nor what provision you shall make for them, what food, what clothes, or how oft they must feed, &c.; will you say God hath not bid you feed or clothe this child, or that servant? It is enough that God chargeth you to provide for your families, in the Scripture; and that in nature he tell you which are your families, and what provision to make for them, and how oft, and in what quantity, &c. And so if God bid you pray in all places, and at all times, on all occasions, (that are fit for prayer,) and experience and common reason tell you that families afford most fit times, place, and occasions for prayer, is not this enough, that there are such seasons, and opportunities, and occasions for family prayer? I refer you to the particular discoveries of them in the beginning, where I proved the dueness of worship in general to be there performed. And I refer you also to common reason itself, not fearing the contradiction of any man whose impiety hath not made him unreasonable, and prevailed against the common light of nature. This first general argument were enough, if men were not so averse to their duty that they cannot know because they will not: but let us therefore add some more.
