Two and a half years later Wesley was taken seriously ill while travelling in Ireland. His friends in London were hourly expecting to hear of his death. Charles Wesley, full of distress, wrote to Fletcher, apparently requesting him to come to London. This Fletcher gently but decidedly declined to do:
"Should your brother fail on earth, you are called, not only to bear up under the loss of so near a relative, but, for the sake of your common children in the Lord, you should endeavour to fill up the gap according to your strength. The Methodists will not expect from you your brother's labours; but they have, I think, a right to expect that you will preside over them while God spares you in the land of the living.... And if at any time you should want my mite of assistance, I hope I shall throw it into the treasury with the simplicity and readiness of the poor widow."
But Wesley recovered, and the call for Fletcher's services never came. Wesley's opinion however remained unaltered, that it would have been better in every way for Fletcher to have joined him in itinerating. Years afterwards, when Fletcher was dead, he wrote:
"I can never believe it was the will of God that such a burning and shining light should be hid under a bushel. No; instead of being confined to a country village, it ought to have shone in every corner of our land. He was full as much called to sound an alarm through all the nation as Mr. Whitefield himself; nay, abundantly more so, seeing he was far better qualified for that important work. He had a more striking person, equally good breeding, an equally winning address, together with a richer flow of fancy, a stronger understanding, a far greater treasure of learning, both in languages, philosophy, philology, and divinity; and, above all (which I can speak with fuller assurance, because I had a thorough knowledge both of one and the other), a more deep and constant communion with the Father and with the Son Jesus Christ.
"And yet let not any one imagine that I depreciate Mr. Whitefield, or undervalue the grace of God and the extraordinary gifts which his great Master vouchsafed unto him. I believe he was highly favoured of God; yea, that he was one of the most eminent ministers that has appeared in England, or perhaps in the world, during the present century. Yet I must own I have known many fully equal to Mr. Whitefield, both in holy tempers and holiness of conversation; but one equal herein to Mr. Fletcher I have not known, no, not in a life of fourscore years."
It was, further, Wesley's belief that an itinerant life would improve Fletcher's health, which was now seriously affected. His letters had for some time contained allusions to frequent infirmities. To one correspondent he says: "My throat is not formed for the labours of preaching. When I have preached three or four times together, it inflames and fills up; and the efforts which I am then obliged to make heat my blood."
To the same, a few months later: "Oh, how life goes! I walked, now I gallop into eternity. The bowl of life goes rapidly down the steep hill of time." To Charles Wesley he writes: "Old age comes faster upon me than upon you. I am already so gray-headed, that I wrote to my brother to know if I am not fifty-six instead of forty-six.... I have had for some days the symptoms of an inward consumptive decay, spitting blood, etc. Thank God! I look at our last enemy with great calmness." Wesley confidently recommended a remedy of which he had more experience than any man then living in England, viz. a long journey on horseback. He proposed that Fletcher should accompany him on a journey of some months, telling him, "When you are tired, or like it best, you may come into my carriage; but remember that riding on horseback is the best of all exercises for you, so far as your strength will permit." Fletcher willingly accepted the proposal, and travelled with Wesley nearly 1200 miles. But after a while certain friends ("kind, but injudicious," Wesley calls them) persuaded him to remain at Stoke Newington, that he might be properly nursed, and have the best medical aid that could be procured. Wesley characteristically remarks, "I verily believe, if he had travelled with me, partly in the chaise and partly on horseback, only a few months longer, he would have quite recovered his health." We are constrained to think that Fletcher was not in a condition to profit by his friend's heroic remedies. He was indeed very ill. Earnest prayers for his recovery were offered at Madeley and elsewhere. A hymn which was composed for the occasion, and sung with deep feeling in Madeley church, contains the following lines:
"Restore him, sinking to the grave;
Stretch out Thy arm, make haste to save;
Back to our hopes and wishes give,
And bid our friend and father live."
For several months he was under the care of his faithful friends Mr. and Mrs. Greenwood, of Stoke Newington. Rest and silence were enjoined, but it was found impossible to restrain him altogether from speaking. One who was much with him says: "The fire which continually burned in his heart many waters could not quench. It often burst out unawares. And then how did we wonder (like those who formerly heard his Lord) 'at the gracious words which proceeded out of his mouth.' ...
"It was in these favoured moments of converse that we found, in a particular manner, the reward which is annexed to receiving a prophet in the name of a prophet. And in some of these lie mentioned circumstances which, as none knew them but himself, would otherwise have been buried in oblivion.
