Wesley preached tirelessly for decades despite physical hardship and neglect.
Among other features in the character of Mr. Wesley, which manifested his devotedness to the great work in which he had engaged, it is said that he ever retained a cheerful insensibility to pain, and even to neglect. As he was traveling with John Nelson, one of his preachers, from common to common, in Cornwall, and preaching to a people who heard him willingly, but seldom or never offered him the slightest hospitality, he one day stopped his horse at some brambles, to pick the fruit. "Brother Nelson," said he, as he did so, "we ought to be thankful that there are plenty of blackberries; for this is the best country I ever saw for getting a stomach, but the worst I ever knew for getting food. Do the people think we can live upon preaching?" "At that time," says his companion, "Mr. Wesley and I slept on the floor; he had a great coat for his pillow, and I had Burkitt's Notes on the New Testament for mine. One morning, about three o'clock, Mr. Wesley turned over, and finding me awake, clapped me on the side, saying, 'Brother Nelson, let us be of good cheer; I have one whole side yet; for the skin is off but on one side.'"
For more than fifty years, in succession, this eminent man generally delivered two, and frequently three or four sermons in a day. But calculating at the lowest estimate, and allowing fifty annually for extraordinary occasions, the whole number, during this period, will be forty thousand five hundred and sixty. To these may be added innumerable exhortations to the societies after preaching, and in other occasional meetings at which he assisted or presided. His journeys, in the work of the ministry, during so long a period, were extraordinary, and probably, on the whole, without a precedent. He traveled about four thousand five hundred miles every year, on an average; and thus, in his long course, he passed over two hundred and twenty-five thousand miles, on his errand of mercy, after he became an itinerant preacher. In addition to all which, the publications which he either wrote, or otherwise prepared for the press, were very numerous. It would have been impossible for him to perform this almost incredible degree of labor, without great punctuality and care in the management of his time. He had stated hours for every purpose, and his only relaxation was a change of employment. His talents for managing complex affairs, and governing a numerous body, dissimilar in its parts, and widely diffused throughout the whole nation, were displayed in the order which he introduced into the societies he had formed, the control which he exercised over them, and the plans he devised and executed for the continuance of that economy which he had established among them.
