In the First Edition of this work, having no expectation of the success which God has, in his goodness, been pleased to give it, I had, for the greater part, performed my office perfunctorily, as is usual in trivial undertakings. But when I perceived that almost all the godly had received it with a favour which I had never dared to wish, far less to hope for, being sincerely conscious that I had received much more than I deserved, I thought I should be very ungrateful if I did not endeavour, at least according to my humble ability, to respond to the great kindness which had been expressed towards me, and which spontaneously urged me to diligence. I therefore ask no other favour from the studious for my new work than that which they have already bestowed upon me beyond my merits. I feel so much obliged, that I shall be satisfied if I am thought not to have made a bad return for the gratitude I owe. This return I would have made much earlier, had not the Lord, for almost two whole years, exercised me in an extraordinary manner. But it is soon enough if well enough. I shall think it has appeared in good season when I perceive that it produces some fruit to the Church of God. I may add, that my object in this work was to prepare and train students of theology for the study of the Sacred Volume, so that they might both have an easy introduction to it, and be able to proceed in it, with unfaltering step, seeing I have endeavoured to give such a summary of religion in all its parts, and have digested it into such an order as may make it not difficult for any one, who is rightly acquainted with it, to ascertain both what he ought principally to look for in Scripture, and also to what head he ought to refer whatever is contained in it. Having thus, as it were, paved the way, I shall not feel it necessary, in any Commentaries on Scripture which I may afterwards publish, to enter into long discussions of doctrines or dilate on common places, and will, therefore, always compress them. In this way the pious reader will be saved much trouble and weariness, provided he comes furnished with a knowledge of the present work as an essential prerequisite. As my Commentary on the Epistle to the Romans will give a specimen of this plan, I would much rather let it speak for itself than declare it in words. Farewell, dear reader, and if you derive any fruit from my labours, give me the benefit of your prayers to the Lord.
