A minister's long-term impact is seen in people converted decades earlier remembering his ministry.
The Rev. Thomas Jackson, of Stockwell, in the memoir of Mr. Hill, furnished to the Evangelical Magazine, states:—Perhaps no man in modern times has been more honored than Mr. Hill, as the instrument of converting souls; his talent appeared more particularly in awakening the careless; instances of which the writer has had many opportunities of witnessing; and he does not remember ever having stayed two days with Mr. H. in any town, without meeting with one person or more to whom his ministry had been made useful. One case, among many, he cannot omit: the scene occurred at Devonport, Devonshire, after Mr. H. had been preaching a missionary sermon to a crowded congregation in the large chapel in Prince's street. The people had withdrawn, and the deacons and a few friends had retired, with Mr. H., into the vestry, when two tall, venerable looking men, upwards of seventy years of age, appeared at the vestry door. After a short pause they entered, arm-in-arm, and advanced towards Mr. H., when one of them said, with some degree of trepidation, "Sir, will you permit two old sinners to have the honor to shake you by the hand?" He replied, with some reserve, "Yes, sir!" when one of these gentlemen, the other hanging on his arm, took his hand, kissed it, bathed it with his tears, and said, "Sir, do you remember preaching on the spot where this chapel now stands, fifty years ago?" "Yes, I do," was the reply. The old man then proceeded to say, "Oh, sir! never can the dear friend who has hold of my arm, or myself, forget that sermon; we were then two careless young men, in his majesty's dock-yard, posting to destruction as fast as time and sin could convey us thither. Having heard that an interesting young clergyman was to preach out of doors, we determined to go and have some fun; accordingly we loaded our pockets with stones, intending to pelt you; but, sir, when you arrived, our courage failed, and as soon as you engaged in prayer, we were so deeply moved that our purpose wavered, and as soon as you began to speak, the word came with power to our hearts; the big tears rolled down our cheeks; we put our hands in our pockets, and dropped the stones one after another, until they were all gone; for God had taken the stone out of our hearts. When the service was over, we retired; but our hearts were too full to speak, until we came near to our lodgings, when my friend at my elbow said, 'John, this will not do; we are both wrong; good night.' This was all he could utter; he retired to his apartment, I to mine; but neither of us dared to go to bed, lest we should awake in hell; and from that time, sir, we humbly hope we were converted to God, who, of his infinite mercy, has kept us in his ways to the present moment; and we thought, sir, if you would permit us, after the lapse of half a hundred years, to have the pleasure of shaking you by the hand before we go home, it would be the greatest honor that could be conferred on us." Mr. H. was deeply affected; the tears rolled down his venerable cheeks in quick succession; he fell on the necks of the old men quite in the patriarchal style; and there you might have seen them, locked in each others' arms, weeping tears of holy joy and gratitude to the Father of mercies. It was a scene at which Gabriel might have rejoiced, and infidelity must have turned pale. The writer is aware that he cannot do justice to it by his description, though he feels, at this distance of time, something like celestial pleasure in recording what he then witnessed.
