On Sunday, June 12th, Mr Alexander Fullerton preached in the Wesleyan chapel at Hyde Park, one of the leaders gave an account of the revival at Ballyclare and Ballynure, and an opportunity was afforded some converts who were present of witnessing for Christ. While one of these, a lad of fourteen from Ballyclare, gave an account of his conversion, and, with tears, entreated the people to come to the Saviour, another lad began to sob and weep. The young convert then ran forward, caught the penitent in his arms, and besought him to look to Jesus, and he would be saved. The affection of the boy seemed to break down the hearts of the people; one general cry burst forth from the congregation, and sinners fell all around, confessing their sins and imploring pardon. The saved of the Lord were many, and they were but the first-fruits of a glorious harvest. Meetings were conducted in the chapel every night for seven or eight weeks, and there was scarcely a service at which souls were not converted. At one of these meetings a gay and thoughtless youth, named Andrew M'Ilwaine, when he saw the people falling clown on all sides, fled from the house, lest he should also be compelled to yield, and remembering an appointment with a comrade in another part of the country, hastened thither to find his friend converted, and he himself in the very condition he had dreaded. Thus he was led to the Saviour and began a course of Christian labour, which eventuated in his entering the Methodist itinerancy.
