While Whitefield was preaching to his large congregations on Kennington Common and in Moorfields, Wesley was similarly employed at Bristol and Kingswood. It is a curious fact that, though Whitefield was forbidden to preach in Newgate Prison, Bristol, Wesley was admitted. Another notable incident must be mentioned. In Bristol and its neighbourhood, Wesley was daily witnessing the most remarkable conversions,--conversions accompanied by those mysterious convulsions that have perplexed all his biographers. In London, Whitefield had prodigious congregations, and his oratorical powers were far greater than those of his friend Wesley; but where were his conversions? His congregations were often powerfully affected; and, on May 12th, he speaks of "many" coming to him, and telling him "what God had done for their souls by his preaching in the fields;" but this, in substance, is all that he himself records. Perhaps this difference in ministerial results may be accounted for by the fact, that nearly the whole of the conversions under Wesley's ministry took place in the meetings of the Religious Societies, where united prayer was always joined to scriptural exposition. On the other hand, during this month of May, Whitefield devoted himself almost exclusively to the work of preaching to vast crowds in the open air, where private spiritual enquiries and united prayers for penitents were impracticable. Besides, at the first, Whitefield strongly objected to such conversions as his friend Wesley was witnessing; and plainly told him that, though he doubted not that God was in the work, yet he equally believed the devil was interposing. He wrote:-- "Were I to give so much encouragement to those convulsions as you have given, how many would cry out every night? I think it is tempting God to require such signs."[217] [217] _Methodist Magazine_, 1849, p. 165. Whitefield, however, was not without conversions; and two notable instances must be mentioned here. Wesley, a few months before he died, said, "Joseph Humphreys was the first lay preacher that assisted me in England, in the year 1738."[218] Who was Joseph Humphreys? The following particulars are gleaned from a pamphlet of forty-four pages, published in 1742, and entitled, "An Account of Joseph Humphreys' Experience of the Work of Grace upon his Heart. Bristol: printed by Felix Farley." [218] Wesley's Works, vol. iv., p. 473. I incline to think this date is not correct.--L. T.
