understand what maketh a duty greatest. Usually that is greatest which tendeth to the greatest good; yet sometimes that is greatest at that time which cannot be done at another time, when others may. Praying, in itself considered, is better than ploughing, or marketing, or conference; and yet these may be greater than it in their proper seasons; because prayer may be done at another time, when these cannot. _Direct._ VI. Let family worship be performed constantly and seasonably, twice a day, at that hour which is freest in regard of interruptions; not delaying it without just cause. But whenever it is performed, be sure it be reverently, seriously, and spiritually done. If greater duty hinder not, begin with a brief invocation of God's name, and craving of his help and blessing through Christ; and then read some part of the holy Scripture in order; and either help the hearers to understand it and apply it, or if you are unable for that, then read some profitable book to them for such ends; and sing a psalm, (if there be enough to do it fitly,) and earnestly pour out your souls in prayer. But if unavoidable occasions will not give way to all this, do what you can, especially in prayer, and do the rest another time; but pretend not necessity against any duty, when it is but unwillingness or negligence. The lively performance of family duties, is a principal means to keep up the power and interest of godliness in the world; which all decays when these grow dead, and slight, and formal. _Direct._ VII. Renew the actual intention and remembrance of your ultimate end, when you set yourselves to your day's work, or set upon any notable business in the world. Let HOLINESS TO THE LORD be written upon your hearts in all that you do. Do no work which you cannot entitle God to, and truly say he set you about; and do nothing in the world for any other ultimate end, than to please, and glorify, and enjoy him. And remember that whatever you do, must be done as a means to these, and as by one that is that way going on to heaven. All your labour must be as the labour of a traveller, which is all for his journey's end; and all your respect or affection to any place or thing in your way, must be in respect to your attainment of the end; as a traveller loveth a good way, a good horse, a good inn, a dry cloak, or good company; but nothing must be loved here as your end or home. Lift up your hearts to heaven and say, If this work and way did not tend thither directly or indirectly, it were no work or way for me. Whatever you do, do all to the glory of God, 1 Cor. x. 31.
