In all this, and much more that followed, or is unrecorded, Henry Martyn was being prepared unconsciously for his formal and unanswered controversies with the learned Mussulmans of Persia. His letters to Corrie tell of his farther experience with his moonshis and the moulvies of Patna, and describe the true spirit of such 'disputings' for the truth. _1807, April 28._--Of what importance is our walk in reference to our ministry, and particularly among the natives. For myself, I never enter into a dispute with them without having reason to reflect that I mar the work for which I contend by the spirit in which I do it. During my absence at Monghyr moonshi went to a learned native for assistance against an answer I had given him to their main argument for the Koran, and he not being able to render it, they mean to have down their leading man from Benares to convince me of the truth of their religion. I wish a spirit of inquiry may be excited, but I lay not much stress upon _clear arguments_; the work of God is seldom wrought in this way. To preach the Gospel, with the Holy Ghost sent down from heaven, is a better way to win souls. _May 4._--I am preparing for the assault of this great Mohammedan Imaum. I have read the Koran and notes twice for this purpose, and even filled whole sheets with objections, remarks, questions, etc.; but, alas! what little hopes have I of doing him or any of them good in this way! Moonshi is in general mute. _October 28._--At night, in a conversation with Mirza accidentally begun, I spoke to him for more than three hours on Christianity and Mohammedanism. He said there was no passage in the Gospel that said no prophet shall come after Christ. I showed him the last verse in Matthew, the passages in Isaiah and Daniel, on the eternity of Christ's kingdom, and proved it from the nature of the way of salvation in the Gospel. I then told him my objections against Mohammedanism, its laws, its defects, its unnecessariness, the unsuitableness of its rewards, and its utter want of support by proof. When he began to mention Mahomet's miracles, I showed him the passages in the 6th and 13th chapters of the Koran, where he disavows the power. Nothing surprised him so much as these passages; he is, poor man, totally indifferent about all religion; he told me that I had produced great doubt in his mind, and that he had no answer to give.
