It appeared to him that by this remarkable event Providence called him home. Accordingly, though he had other preferments offered him in the army, he chose to return, and I believe the more willingly, as he did not expect there would have been an action. Just at this time it pleased God to give him an awful instance of the uncertainty of human prospects and enjoyments, by that violent fever which seized him at Ghent on his way to England, and perhaps the more severely for the efforts he made to push on his journey, though he had for some days been much indisposed. It was, I think, one of the first fits of severe illness he had ever met with, and he was ready to look upon it as a sudden call into eternity; but it gave him no painful alarm in that view. He committed himself to the God of his life, and in a few weeks he was so well recovered as to be capable of pursuing his journey, though not without difficulty. I cannot but think it might have conduced much to a more perfect recovery than he ever attained, to have allowed himself a longer repose, in order to recruit his exhausted strength and spirits. But there was an activity in his temper not easy to be restrained, and it was now stimulated, not only with a desire to see his friends, but of being with his regiment, that he might omit nothing in his power to regulate their morals and their discipline, and to form them for public service. Accordingly, about the middle of June, 1743, he passed through London, where he had the honour of waiting on their royal highnesses, the Prince and Princess of Wales, and of receiving from both the most obliging token of favour and esteem. He arrived at Northampton on Monday the 21st of June, and spent part of three days there. But the great pleasure which his return and preferment gave us, was much abated by observing his countenance so sadly altered, and the many marks of languor and remaining disorder which evidently appeared, so that he really looked ten years older than he had done ten months before. I had, however, a satisfaction sufficient to counterbalance much of the concern which this alteration gave me, in a renewed opportunity of observing, indeed more sensibly than ever, in how remarkable a degree he was dead to the enjoyments and views of this mortal life. When I congratulated him on the favourable appearances of Providence for him in the late event, he briefly told me the remarkable circumstances that attended it, with the most genuine expressions of gratitude to God for them; but added, "that as his account was increased with his income, power, influence, and his cares were proportionably increased too, it was, as to his own personal concern, much the same to him whether he had remained in his former station, or been elevated to this; but that if God should by this means honour him as an instrument of doing more good than he could otherwise have done, he should rejoice in it."

I perceived that the near views he had taken of eternity, in the illness from which he was then so imperfectly recovered, had not in the least alarmed him; but that he would have been entirely willing, had such been the determination of God, to have been cut short in a foreign land, without any earthly friend near him, and in the midst of a journey undertaken with hopes and prospects so pleasing to nature, which appeared to me no inconsiderable evidence of the strength of his faith. But we shall wonder the less at this extraordinary resignation, if we consider the joyful and assured prospect which he had of a happiness infinitely superior beyond the grave; of which that worthy minister of the church of Scotland, who had an opportunity of conversing with him quickly after his return, and having the memorable story of his conversion from his own mouth, (as I have hinted above,) writes thus in his letter to me, dated Jan. 14, 1746-7:
"When he came to review his regiment at Linlithgow, in summer 1743, after having given me the wonderful story as above, he concluded in words to this purpose: Let me die whenever it shall please God, or wherever it shall be, I am sure I shall go to the mansions of eternal glory, and enjoy my God and my Redeemer in heaven for ever."

While he was with us at this time he appeared deeply affected with the sad state of things as to religion and morals, and seemed to apprehend that the rod of God was hanging over so sinful a nation. He observed a great deal of disaffection which the enemies of the government had, by a variety of artifices, been raising in Scotland for some years; and the number of Jacobites there, together with the defenceless state in which our island then was, with respect to the number of its forces at home, (of which he spoke at once with great concern and astonishment,) led him to expect an invasion from France, and an attempt in favour of the Pretender, much sooner than it happened. I have heard him often say, many years before it came so near being accomplished, "that a few thousands might have a fair chance for marching from Edinburgh to London uncontrolled, and throw the whole Kingdom into an astonishment." And I have great reason to believe that this was one main consideration which engaged him to make such haste to his regiment, then quartered in those parts, as he imagined there was not a spot of ground where he might be more likely to have a call to expose his life in the service of his country, and perhaps, by appealing on a proper call early in its defences, be instrumental in suppressing the beginnings of most formidable mischief. How rightly he judged in these things, the event too evidently showed.

The evening before our last separation, as I knew I could not more agreeably entertain the valuable friend who was then my guest, I preached a sermon in my own house, with some peculiar reference to his case and circumstances, from those ever-memorable words, than which I have never felt any more powerful and more comfortable: Psalm xci. 14, 15, 16, "Because he hath set his love upon me, therefore will I deliver him: I will set him on high, because he hath known my name. He shall call upon me, and I will answer him; I will be with him in trouble, I will deliver him, and honour him: with long life (or length of days) will I satisfy him, and show him my salvation." This scripture could not but lend our meditations to survey the character of the good man, as one who so knows the name of the blessed God––has such a deep apprehension of the glories and perfections of his nature––as determinately to set his love upon him, to make him the supreme object of his most ardent and constant affection. And it suggested the most sublime and animating hopes to persons of such a character, that their prayers shall be always acceptable to God; that though they may, and must, be called to their share in the troubles and calamities of life, yet they may assure themselves of the divine presence in all, which will issue in their deliverance, in their exaltation, sometimes in distinguished honour and esteem among men, and, it may be, in a long course of useful and happy years on earth; at least, which shall undoubtedly end in seeing, to their perpetual delight, the complete salvation of God, in a world where they shall enjoy length of days for ever and ever, and employ them all in adoring the great Author of their salvation and felicity. It is evident that these natural thoughts on such a Scripture were matters of universal concern. Yet had I, as a minister of the gospel, known that this was the last time I should address Colonel Gardiner, and had I foreseen the scenes through which God was about to lead him, I hardly know what considerations I could have suggested with more peculiar propriety. The attention, elevation, and delight with which he heard them, were very apparent, and the pleasure which the observation of it gave me, continues to this moment.

Let me be permitted to digress so far as to add, that this is indeed the great support of a Christian minister under the many discouragements and disappointments which he meets with in his attempts to fix upon the profligate or the thoughtless part of mankind a deep sense of religious truth; that there is another important part of his work in which he may hope to be more generally successful; as, by plain, artless, but serious discourses, the great principles of Christian duty and hope may be nourished and invigorated in good men, their graces watered as at the root, and their souls animated, both to persevere and improve in holiness. When we are effectually performing such benevolent offices, so well suiting our immortal natures, to persons whose hearts are cemented with ours in the hands of the most endearing and sacred friendship, it is too little to say that it overpays the fatigue of our Labours; it even swallows up all sense of it in the most rational and sublime pleasure.

An incident occurred that evening, which, at least for the oddness of it, may deserve a place in these memoirs. I had then with me one Thomas Porter, a poor but very honest and religious man, (now living at Hatfield Broad-Oak in Essex,) who is quite unacquainted with letters, so as not to be able to distinguish one from another, yet is master of the contents of the Bible in so extraordinary a degree, that he has not only fixed an immense number of texts in his memory, but, merely by hearing them quoted in sermons, has registered there the chapter and verse in which these passages are to be found. This is attended with a marvellous facility in directing readers to turn to them, and a most unaccountable talent of fixing on such as suit almost every imaginable variety of circumstances in common life. There are in this case two considerations that make it the more wonderful; the one, that he is a person of very low genius, having, besides a stammering which makes his speech almost unintelligible to strangers, so wild and awkward a manner of behaviour, that he is frequently taken for an idiot, and seems in many things to be indeed so;––the other, that he grew up to manhood in a very licentious course of living, and an entire ignorance of divine things, so that all these exact impressions on his memory have been made in his riper years. I thought it would not be disagreeable to the colonel to introduce to him this odd phenomenon, which many hundreds of people have had a curiosity to examine; and, among all the strange things I have seen in him, I never remember any that equalled what passed on this occasion. On hearing the colonel's profession, and receiving some hints of his religious character, he ran through a vast variety of scriptures, beginning at the Pentateuch and going on to the Revelation, relating either to the dependence to be fixed on God for the success of military preparations, or to the instances and promises occurring there for his care of good men in the most imminent dangers, or to the encouragement to despise perils and death, while engaged in a good cause, and supported by the views of a happy immortality. I believe he quoted more than twenty of these passages, and I must freely own that I know not who could have chosen them with greater propriety. If my memory deceive me not, the last of this catalogue was that from which I afterwards preached, on the lamented occasion of this great man's fall: "Be thou faithful unto death, and I will give thee a crown of life." We were all astonished at so remarkable a feat, and I question not but many of my readers will think the memory of it worthy of being thus preserved.

But to return to my main subject: The day after the sermon and conversation of which I have been speaking, I took my best leave of my inestimable friend, after attending him some part of his way northward. The first stage of our journey was to the cottage of that poor but religious family which I had before occasion to mention as relieved, and indeed in a great measure subsisted by his charity. Nothing could be more delightful than to observe the condescension with which he conversed with these his humble pensioners. We there put up our last united prayers together; and he afterwards expressed, in the strongest terms I have ever heard him use on such an occasion, the singular pleasure with which he had joined in them. Indeed it was no small satisfaction to me to have an opportunity of recommending such a valuable friend to the divine protection and blessing, with that particular freedom and enlargement on what was peculiar in his circumstances, which hardly any other situation, unless we had been quite alone, could so conveniently have admitted. We went from thence to the table of a person of distinction in the neighborhood, where he had an opportunity of showing in how decent and graceful a manner he could unite the Christian and the gentleman, and give conversation an improving and religious turn, without violating any of the rules of polite behaviour, or saying or doing any thing, which looked at all constrained or affected. Here we took our last embrace, committing each other to the care of the God of heaven; and the colonel pursued his journey to the north, where he spent the remainder of his days.

The more I reflect upon this appointment of Providence, the more I discern the beauty and wisdom of it––not only as it led directly to that glorious period of life with which God had determined to honour him, and in which, I think, it becomes all his friends to rejoice, but also as the retirement on which he entered could not but have a happy tendency to favour his more immediate and complete preparation for so speedy a remove. To this we may add, that it must probably have a very powerful influence to promote the interests of religion (incomparably the greatest of all interests) among the members of his own family, who must surely be edified by such daily lessons as they received from his lips, when they saw them illustrated and enforced by so admirable an example, and for two complete years. It is the more remarkable, as I cannot find from the memoirs of his life in my hands that he had ever been so long at home since he had a family, or indeed, from his childhood, ever so long at a time in any one place.

With how clear a lustre his lamp shone, and with what holy vigour his loins were girded up in the service of his God in these his latter days, I learn in part from the letters of several excellent persons in the ministry, or in secular life, with whom I have since conversed or corresponded. In his many letters dated from Bankton during this period, I have still further evidence how happy he was amidst those infirmities of body, which his tenderness for me would seldom allow him to mention; for it appears from them what a daily intercourse he kept up with Heaven, and what delightful communion with God crowned his attendance on public ordinances, and his sweet hours of devout retirement. He mentions his sacramental opportunities with peculiar relish, crying out, as in a holy rapture, in reference to one and another of them, "Oh how gracious a Master do we serve! how pleasant is his service; how rich the entertainments of his love! yet how poor and cold are our services!" But I will not multiply quotations of this sort after those I have given above, which may be a sufficient specimen of many more in the same strain. This hint may suffice to show that the same ardour of soul held out in a great measure to the last; and indeed it seems that towards the close of life, like the flame of a lamp almost expiring, it sometimes exerted an unusual blaze.

He spent much of his time at Bankton in religious solitude; and one most intimately conversant with him assures me that the traces of that delightful converse with God which he enjoyed in it might easily be discerned in the solemn yet cheerful countenance with which he often came out of his closet. Yet his exercises there must sometimes have been very mournful, considering the melancholy views which he had of the state of our public affairs.
