That the doctrine of Original Sin is one of the fundamental truths of our Christian profession has been always owned in the Church of God. And an especial part it is of that peculiar possession of truth, which they enjoy, whose religion towards God is built upon, and resolved into Divine Revelation. As the world by its wisdom never knew God aright, so the wise men of it were always utterly ignorant of this inbred evil in themselves and others. With us the doctrine and conviction of it lie in the very foundation of all wherein we have to do with God, in reference to our pleasing of him here, or obtaining the enjoyment of him hereafter. It is also known what influence it has into the great truths concerning the Person of Christ, his mediation, the fruits and effects of it, with all the benefits that we are made partakers of thereby. Without a supposition of it, not any of them can be truly known, or savingly believed. For this cause has it been largely treated of by many holy and learned men, both of old and of latter days. Some have laboured in the discovery of its nature, some of its guilt and demerit; by whom also the truth concerning it has been vindicated from the opposition made to it, in the past and present ages. By most these things have been considered in their full extent and latitude, with respect to all men by nature, with the estate and condition of them who are wholly under the power and guilt of it. How thereby men are disenabled and incapacitated in themselves to answer the obedience required either in the Law, or the Gospel, so as to free themselves from the curse of the one or to make themselves partakers of the blessing of the other, has been by many also fully evinced. Moreover, that there are remainders of it abiding in believers after their regeneration and conversion to God, as the Scripture abundantly testifies; so it has been fully taught and confirmed; as also how the guilt of it is pardoned to them, and by what means the power of it is weakened in them. All these things I say have been largely treated on, to the great benefit and edification of the Church. In what we have now in design, we therefore take them all for granted, and endeavour only farther to carry on the discovery of it in its actings and oppositions to the Law and Grace of God in believers. Neither do I intend the discussing of any thing that has been controverted about it. What the Scripture plainly reveals and teaches concerning it, what believers evidently find by experience in themselves, what they may learn from the examples and acknowledgments of others, shall be represented in a way suited to the capacity of the meanest and weakest who is concerned therein. And many things seem to render the handling of it at this season not unnecessary. The effects and fruits of it which we see in the apostasies and backslidings of many, the scandalous sins and miscarriages of some, and the course and lives of the most, seem to call for a due consideration of it. Besides, of how great concernment a full and clear acquaintance with the power of this indwelling sin (the matter designed to be opened) is to believers, to stir them up to watchfulness and diligence, to faith and prayer, to call them to repentance, humility, and self-abasement, will appear in our progress. These in general were the ends aimed at in the ensuing discourse, which being at first composed and delivered for the use and benefit of a few, is now by the providence of God made public. And if the reader receive any advantage by these weak endeavours, let him know that it is his duty, as to give glory to God, so to help them by his prayers, who in many temptations and afflictions are willing to labor in the vineyard of the Lord, to which work they are called.
