Dined with Mr. Wilberforce at Palace Yard. It was very agreeable, as there was no one else. Speaking of the slave trade, I mentioned the words, 'Shall I not visit for these things?' and found my heart so affected that I could with difficulty refrain from tears. Went with Mr. W. to the House of Commons, where I was surprised and charmed with Mr. Pitt's eloquence. Ah, thought I, if these powers of oratory were now employed in recommending the Gospel! On his way back to Cambridge, through London, he Went to St. Paul's, to see Sir W. Jones's monument; the sight of the interior of the dome filled my soul with inexpressible ideas of the grandeur of God, and the glory of heaven, much the same as I had at the sight of a painted vaulted roof in the British Museum. I could scarcely believe that I might be in the immediate enjoyments of such glory in another hour. In the evening the sound of sacred music, with the sight of a rural landscape, imparted some indescribable emotions after the glory of God, by diligence in His work. To preach the Gospel for the salvation of my poor fellow-creatures, that they might obtain the salvation which is in Christ Jesus, with eternal glory, seemed a very sweet and precious employment. Lydia then, again, seemed a small hindrance. His duties as examiner, tutor, and in charge of Lolworth, and home mission work in Wall's Lane, the hospital and almshouse, left him little leisure, and that he gave to the Bengali grammars of Halhed and Carey, to Carey's Bengali New Testament, to Arabic grammars, and to the missionary accounts in the _Christian Observer_, for which, also, he wrote. Referring, evidently, to Carey's convert, he wrote: The account of a Brahmin preaching the Gospel delighted me most exceedingly. I could not help blessing God for thus glorifying Himself.... I was much pained and humbled at reflecting that it has never yet, to my knowledge, pleased God to awaken one soul by my means, either in public or private,--shame be to myself. Simeon gave me a letter from Mr. Brown of Calcutta, which gave me great delight on many accounts. Speaking of me, he says, 'Let him marry, and come out at once.' I thought of Lydia with great tenderness, but without pain at my determination to go out single. I found great affection in prayer for my dear brethren at Calcutta, for the establishing of Christ's Kingdom among the poor Gentiles, and for my being sent among them, if it were His will. Thinking my mind was in need of recreation, I took up Lord Teignmouth's _Life of Sir William Jones_, and read till tea. Low spirits at church, through being about to preach old sermons, which I feel so ashamed of offering to God, that I believe I shall rather leave everything undone, than not write one new one at least every week.
