None of six letters from Lydia Grenfell have been preserved, but we find in her Diary more self-revealing of her heart than could be made to Henry Martyn, and also more severity in judging of herself as in the presence of God.
1806, May 23.—Wrote dear H. I have felt to-day a return of spirits, but have spent them too much in worldly things. I found it a blessed season in prayer, yet I fear whether my satisfaction did not rather arise from being enabled to pray than from any extraordinary communications from above. O Lord, search and try my heart, let not its deceitfulness impose on me.
July 19.—Thought much this week of my dear absent friend.
August 2.—My family’s unhappiness preys on my mind—sister burning with anger and resentment against sister, brother against brother, a father against his children. Oh, what a picture! Let me not add to the weight of family sin.
August 4.—Passed a happy day. Read Baxter, and found in doing so my soul raised above. Oh, let me have, blessed Lord, anticipations of this blessedness and foretaste of glory. In Thy presence above I shall be reunited to Thy dear saint, now labouring in Thy vineyard in a distant land. One year is nearly passed since we parted, but scarcely a waking hour, I believe, has he been absent from my mind. In general my remembrance of him is productive of pleasure—that I should possess so large a share of his affection, and be remembered in his prayers, and have an eternity to spend with him, yielding me in turn delightful pleasing meditations; but just now nature grieves that we are no more to meet below; yet, O my blessed Father, I cry, ‘Thy will be done, not as I will, but as Thou wilt.’
August 10.—Went to church. My soul was very dull and inanimate throughout the service—the sermon had nothing in it to enliven or instruct. Barren as this place is for other means of grace, I have the Word and leisure to search; I cannot then complain, but of myself there is cause enough. Oh, how is my soul so earthly? why cannot I rise and dwell above? Tied and bound with the chain of sin, fettered and confined, I can only cast a look above. One year is gone since my dear friend left England. The number of our years of separation is so much lessened, and our salvation draws near.
October 19.—My birthday. One-and-thirty years have I existed on this earth, for twenty-five of which all the amount was sin, vanity, and rebellion against God; the last six, though spent differently, yet for every day in them I am persuaded I have sinned in heart, so as justly to merit condemnation of that God in whose mercy I trust.
November 5.—To-day I was reading of David’s harp driving away the evil spirit from Saul, and resolved again (the Lord helping me) to try the sweet harp of Jesse’s son in my first and last waking thoughts, for sad and disordered are my thoughts upon my friend. The expectation of letters from my dear friend in India by this fleet is almost over, and my mind is rendered anxious about him.
November 25.—My very soul has been cheered by accounts from my dear friend in India, for whom my mind has been greatly anxious. ‘Cast thy cares on Me’ is a command badly attended to by me.
The formal and first request from Henry Martyn to join him in India reached Lydia Grenfell on March 2, 1807. We learn from his reply in October 1807, from Dinapore, that she had sent a refusal in her mother’s name. But, on April 25, the Rev. Charles Simeon called on her with the result which he thus records:
