After thanking Mr. Booth for the present of Jones's work on the Trinity, he thus describes his religious impressions previous to its perusal, and the effect it produced: "Religious polemics, indeed, have seldom formed a part of my studies; though whenever I happened accidentally to turn my thoughts to the subject of the Protestant doctrine of the Godhead, and compared it with Arian and Socinian, many doubts interfered, and I even began to think that the more nicely the subject was investigated, the more perplexed it would appear, and was on the point of forming a resolution to go to heaven in my own way, without meddling or involving myself in the inextricable labyrinth of controversial dispute, when I received and perused this excellent treatise, which finally cleared up the mists which my ignorance had conjured around me, and clearly pointed out the real truth." From the moment he became convinced of the truths of Christianity, all the enthusiasm of his nature was kindled. The ministry only, was deemed worthy of his ambition; and he devoted his thoughts to the sacred office with a zeal that justified a hope of the richest fruits. In a letter to his friend, Mr. Almond, in November, 1803, he says, "My dear friend, I cannot adequately express what I owe to you on the score of religion. I told Mr. Robinson you were the first instrument of my being brought to think deeply on religious subjects; and I feel more and more every day, that if it had not been for you, I might, most probably, have been now buried in apathy and unconcern. Though I am in a great measure blessed,--I mean blessed with faith, now pretty steadfast, and heavy convictions, I am far from being happy. My sins have been of a dark hue, and manifold: I have made Fame my God, and Ambition my shrine. I have placed all my hopes on the things of this world. I have knelt to Dagon; I have worshipped the evil creations of my own proud heart, and God had well nigh turned his countenance from me in wrath; perhaps one step further, and he might have shut me for ever from his rest. I now turn my eyes to Jesus, my Saviour, my atonement, with hope and confidence: he will not repulse the imploring penitent; his arms are open to all, they are open even to me; and in return for such a mercy, what can I do less than dedicate my whole life to his service? My thoughts would fain recur at intervals to my former delights; but I am now on my guard to restrain and keep them in. I know now where they ought to concentre, and with the blessing of God, they shall there all tend.
