William was drawn to seek after God and serve Him as early as the year 1728. He laboured hard and successfully in reviving the charity schools in London, particularly those in Langbourn Ward, Castle Baynard Ward, Billingsgate Ward, Vintry Ward, in the parish of St. George the Martyr, and in Hackney. For the school at the last-mentioned place, he raised, by subscriptions and public collections, an income of £150 per annum, and that notwithstanding the "opposition of the minister, the churchwardens, and the vestrymen of the parish."[167]

In the year 1738, he became acquainted with Charles Wesley and the Methodists, and, in the month of November, found peace with God through faith in Christ. Oddly enough, he was allowed to be present at the Conference of Oxford Methodists, already mentioned, on January 5, 1739.[168] A few weeks afterwards, he became Whitefield's travelling companion; and went with him to America in August, 1739.

William Seward returned to England, not to stay in it, but, 1. To induce Mr. Hutchins, the Oxford Methodist, to take the management of Whitefield's Orphan House in Georgia. 2. To convince the Trustees of Georgia that three things were necessary to establish the Colony, viz.: "an allowance of negroes, a free title to the lands, and an independent magistracy." 3. To collect subscriptions for a negro school in Pennsylvania. And, 4. To bring the money, lodged in the hands of the trustees, for building the church at Savannah.

These were the public reasons why Mr. Seward returned to England; but there were also private reasons. Mr. Seward had bought five thousand acres of land on the forks of Delaware, for which he had paid £2,200 sterling; and he hoped to beg this amount of money in England, and then to give the land for the erection of a negro school, and also a location for a number of "English friends, where," to use Seward's words, "they might worship God in their own way, without being thought Enthusiasts for so doing." He also intended to buy a ship in England for the purpose of conveying the refugees to their foreign home. The place was to be a sort of "Hernhuth" in America. Besides this, William Seward seems to have been a widower with an only daughter, who was being educated by a private governess. He was now desirous to remove his daughter to Georgia, and to complete her education in Whitefield's Orphan House. With reference to this, he wished to buy of the Trustees of Georgia five hundred acres of land adjoining the Orphan House estate, provided he could have a perfect title to leave it to the Orphan House, if he thought desirable.

From this concise statement it will be seen that Mr. Seward had abundance of business to transact in England; but besides all this, there was a family quarrel exceedingly unpleasant. The elder brother, Henry Seward, was wroth at his brothers becoming Methodists. Three months before William's return to England, Benjamin Seward was seriously ill. "His fever was called madness." His letters were intercepted, and his servants set over him as spies. Charles Wesley went to see him, but was not admitted to his presence, and wrote:—"Henry Seward fell upon me without preface or ceremony. I was the downfall of his brother, had picked his pocket, ruined his family, come now to get more money, was a scoundrel, rascal, and so forth, and deserved to have my gown stripped over my ears. He concluded with threatening how he would beat me, if he could but catch me on Bengeworth Common." On the day after this angry interview, Charles Wesley attempted to preach. Henry Seward came and said, "Four constables are ordered to apprehend you if you come near my brother's wall," the place appointed for preaching; "so come at your peril." Charles writes:—

"I walked towards the place. Mr. Henry met me with threats and revilings. I began singing—

'Shall I, for fear of feeble man,
Thy Spirit's course in me restrain?'

He ran about raving like a madman, and quickly got some men for his purpose, who laid hold on me. Henry cried, 'Take him away, and duck him.' I broke out into singing with T. Maxfield, and let them carry me whither they would. At the bridge in the lane, they left me. There I stood out of the liberty of the corporation, and gave out—

'Angel of God, whate'er betide,
Thy summons I obey!'"

Charles then proceeded to preach to a congregation of some hundreds, from the words, "If God be for us, who can be against us?"

Eight days after this, Charles Wesley and Henry Seward had another altercation. The country squire again lost his manners, and after calling the poor Methodist preacher, "rogue, rascal, villain, and pickpocket," actually wrung his nose. Charles departed, rejoicing that he was counted worthy to suffer shame in the cause of Christ.[169]

Three months after this disreputable scene, William Seward arrived in England, and most likely visited his brothers at Badsey. Be that as it may, when William and Charles Wesley met at Bristol, in the month of September following, William was evidently prejudiced against his friend. Charles writes:—

"1740, September 23. Mr. W. Seward came, and was very cordial. We prayed, rejoiced, and gave thanks. If I did not love him the better for his opinion, I am sure it made me more industrious to confirm my old love towards him. I carried him to our colliers. He spoke a few words to them, which did not convince me of his call to preach. In our return, he told me Mrs. Grevil and others had urged him to claim the Room in the Horse-fair,[170] but he abhorred their baseness. Next day, he told me he was in a mist, the Baptists last night having laboured hard to make him oppose me publicly. Before we parted, all was set right again; but a few hours after, he came from the Baptists, and utterly renounced both me and my brother, in bitter words of hatred, which they had put into his mouth."[171]
