_Direct._ XIII. Remember that whatever duty you seem obliged to perform, the obligation still supposeth that it is not naturally impossible to you, and therefore you are bound to do it as well as you can: and when other men's force, or your natural disability, hindereth you from doing it as you would, you are not therefore disobliged from doing it at all; but the total omission is worse than the defective performance of it, as the defective performance is worse than the doing of it more perfectly.[33] And in such a case the defects which are utterly involuntary are none of yours imputatively at all, but his that hindereth you (unless as some other sin might cause that). As if I were in a country where I could have liberty to read and pray, but not to preach, or to preach only once a month and no more; it is my duty to do so much as I can do, as being much better than nothing, and not to forbear all, because I cannot do all.
_Object._ But you must forbear no part of your duty? _Answ._ True: but nothing is my duty which is naturally impossible for me to do. Either I can do it, or I cannot: if I can, I must (supposing it a duty in all other respects); but if I cannot, I am not bound to it.
_Object._ But it is not suffering that must deter you, for that is a carnal reason: and your suffering may do more good than your preaching. _Answ._ Suffering is considerable either as a pain to the flesh, or as an irresistible hinderance of the work of the gospel: as it is merely a pain to the flesh, I ought not to be deterred by it from the work of God; but as it forcibly hindereth me from that work, (as by imprisonment, death, cutting out the tongue, &c.) I may lawfully foresee it, and by lawful means avoid it, when it is sincerely for the work of Christ, and not for the saving of the flesh. If Paul foresaw that the preaching of one more sermon at Damascus was like to hinder his preaching any more, because the Jews watched the gates day and night to kill him, it was Paul's duty to be let down by the wall in a basket, and to escape, and preach elsewhere, Acts ix. 25. And when the christians could not safely meet publicly, they met in secret, as John xix. 38; Acts xii. 12, &c. Whether Paul's suffering at Damascus for preaching one more sermon, or his preaching more elsewhere, was to be chosen, the interest of Christ and the gospel must direct him to resolve: that which is best for the church, is to be chosen.
_Direct._ XIV. Remember that no material duty is formally a duty at all times: that which is a duty in its season, is no duty out of season. Affirmative precepts bind not to all times (except only to habits, or the secret intention of our ultimate end, so far as is sufficient to animate and actuate the means, while we are waking and have the use of reason). Praying and preaching, that are very great duties, may be so unseasonably performed, as to be sins: if forbearing a prayer, or sermon, or sacrament one day or month, be rationally like to procure your help or liberty to do it afterward, when that once or few times doing it were like to hinder you from doing it any more, it would be your duty then to forbear it for that time (unless in some extraordinary case): for even for the life of an ox or an ass, and for mercy to men's bodies, the rest and holy work of a sabbath might be interrupted; much more for the souls of many. Again I warn you, as you must not pretend the interest of the end against a peremptory, absolute command of God, so must you not easily conclude a command to be absolute and peremptory to that which certainly contradicts the end; nor easily take that for a duty, which certainly is no means to that good which is the end of duty, or which is against it. Though yet no seeming aptitude as a means, must make that seem a duty, which the prohibition of God hath made a sin.
_Direct._ XV. It is ever unseasonable to perform a lesser duty of worship, when a greater should be done; therefore it much concerneth you to be able to discern, when two duties are inconsistent, which is then the greater and to be preferred: in which the interest of the end must much direct you; that being usually the greatest which hath the greatest tendency to the greatest good.
_Direct._ XVI. Pretend not one part of God's worship against another, when all, in their place and order, may be done. Set not preaching and praying against each other; nor public and private worship against each other; nor internal worship against external; but do all.
