GOOD READER:
I do confess there are so many godly and learned expositions upon the ten commandments already extant, that it may seem needless to add any more unto that number. Nevertheless, I pray thee, do not think it impossible but that God may, by such a weak instrument as I myself am, show his power in doing something more, touching this subject, than hath yet been done. I do confess, I have had good helps from the labours of others, and have made much use thereof, especially for matter, yet have I not confined my discourse within the compass of what I have found in other books, but have, from the warrant of the word of God, taken the boldness to enlarge it, both as touching the matter and manner, and especially touching the application, wherein I have endeavoured to give both believers and unbelievers their distinct proportion, by distinguishing betwixt the ten commandments, as they are the law of works, having the promise of eternal life, and the threatening of eternal death annexed to them, and so applying them to the unbeliever; and as they are the law of Christ, having the promise of eternal life, and the threatening of eternal death separated from them, and so applying them to the believer. I have not denied, but acknowledged, yea, and proved, that the law of the ten commandments, truly expounded, is to be a perpetual rule of life to all mankind, yea, to believers themselves; for though the Spirit of Jesus Christ do, according to his promise, write this law in their hearts, as their inward rule, yet, in regard that whilst they live in this world, it is done but in part, they have need of the ten commandments to be unto them as an outward rule: for though the Spirit have begotten in them a love to this law, and wrought in them a willing disposition to yield obedience thereunto, yet have they need of the law to be unto them as a glass, wherein they may see what the will of God is, and as a rule to direct them how to actuate their love and willingness, so that, as a precious godly minister of Jesus Christ truly says, the Spirit within, and the law without, "is a lamp unto their feet, and a light unto their path," (Psa 119:105).
But yet I do conceive, that expositors on the commandments should not only endeavour to drive on their designs to that end, and there terminate their endeavours, as if there were no further use to be made of the law, neither in believers nor in unbelievers; but they should aim at a further end—an end beyond this, especially in unbelievers, and that is to discover to them how far short they come of doing that which the law requireth, that so they may not take up their rest in themselves, but hasten out of themselves to Jesus Christ; and that believers, by beholding their own imperfections, should take occasion to humble themselves, and cleave the more close unto him by faith.
For when, by way of exposition, it is only declared what is required, and what is forbidden in every commandment, with exhortations, motives, and means to do thereafter, it has been observed that divers both profane and mere civil honest people, upon the hearing or reading of the same, have concluded with themselves, that they must either alter their course of life, and strive and endeavour to do more than they have done, and better than they have done, or else they shall never be saved; and hereupon they have taken up a form of godliness, in hearing, reading, and praying, and the like, and so have become formal professors, and therein have rested, coming far short of Jesus Christ, yea, and believers themselves have sometimes taken occasion thereby, to conceive that they must do something towards their own justification and salvation.
Wherefore I, yet not I by any power of my own, but by the grace of God that is with me, have endeavoured not only to show what is required, and what is forbidden in every commandment, but also that it is impossible for any man, whether he be an unbeliever or a believer, to keep any one commandment perfectly, yea, or to do any one action or duty perfectly, that so by the working of God's Spirit in the reading of the same, men may be moved; not only to turn from being profane, or mere civil honest men, to be formal professors, but that they may be driven out of all their own works and performances unto Jesus Christ, and so become Christians indeed, and that those who are Christians indeed, may thereby be moved to prize Jesus Christ the more; and if the Lord shall but be pleased to enable either myself or any other man or woman, to make this use of this ensuing Dialogue, then shall not my labour be in vain: but my heart's desire and prayer to God shall be, that many may receive as much good by the "Marrow" which is contained in this second bone, as they say they have done by that which is contained in the first; that so God may be glorified and their souls edified, and then have I my reward. Only let me beg of thee, that for what good thou receivest thereby, thou wilt beg at the throne of grace for me, that my faith may be increased, and so my love inflamed towards God, and towards man for God's sake, and then I am sure I shall keep the law more perfectly than I have yet done. The which that we may all do, the grace of our Lord Jesus Christ be with all our spirits. Amen.
Thine in the Lord Jesus Christ,
