Thus was Whitefield driven to outdoor preaching in London, as well as in Bristol. Perhaps he would have preferred a church; but now he must either preach out of doors, or not at all. His spirit might be vexed, but was not depressed. On the very day when the imperious churchwarden thrust him out of Islington Church into the churchyard, he wrote to his friend Harris at Gloucester:-- "To-day, my Master, by His providence and Spirit, compelled me to preach in the churchyard at Islington. To-morrow, I am to repeat that mad trick, and, on Sunday, to go out into Moorfields. The word of the Lord runs and is glorified. People's hearts seem quite broken. God strengthens me exceedingly. I preach till I sweat through and through. Innumerable blessings does God pour down upon me. Oh that I had a thankful heart!" When Sunday came, Whitefield, not surprisingly, did more than he intended. He writes:-- "Sunday, April 29. Preached in the morning at Moorfields, to an exceeding great multitude. At ten, went to Christ Church, and heard Doctor Trapp preach most virulently against me and my friends, upon these words, 'Be not righteous over-much: why shouldest thou destroy thyself?' God gave me great serenity of mind; but, alas! the preacher was not so calm as I wished him. His sermon was founded upon wrong suppositions, not to say that there were many direct untruths in it. And he argued so strenuously against all _inward feelings_, that he plainly proved that, with all his learning, he knew nothing yet as he ought to know. At five, I preached at Kennington Common, about two miles from London, where thirty thousand people were supposed to be present. The wind carried my voice to the extremest part of the audience. All stood attentive, and joined in the Psalm and the Lord's Prayer most regularly. I scarce ever preached more quietly in any church. The word came with power. The people were much affected. All agreed it was never seen on this wise before. I hope a good inroad has been made into the devil's kingdom this day.[200] [200] _Read's Weekly Journal_ of May 5th, says Whitefield preached from the same text as Dr. Trapp, and adds, "As the people were kept waiting a long time for the preacher, Dr. Rock cunningly took the advantage of his absence, and talked so pathetically to the multitude of the efficacy of his packets, that he disposed of abundance of them; and it is thought the quack for the body made greater profit that afternoon than the quack for the soul."
