Henry Martyn was a young missionary to India and Arabia and Persia in the early 1800's. He had left his fiance Lydia Grenfell behind in England in 1806 and would never see her again — he died at 31.
On the boat he fought back self-pity and discouragement with the promises of God's word. He arrived in Calcutta in May and two months later had a devastating experience. One of the veteran missionaries preached a sermon directed against Henry Martyn and his doctrines. He called his teaching inconsistent, extravagant, and absurd. He accused him of seeking only to "gratify self-sufficiency, pride and uncharitableness."
Martyn's answer comes in his own journal:
"In the multitude of my troubled thoughts I still saw that there is a strong consolation in the hope set before us. Let men do their worst, let me be torn to pieces, and my dear Lydia torn from me; or let me labour for fifty years amidst scorn, and never seeing one soul converted; still it shall not be worse for my soul in eternity, nor worse for it in time. Though the heathen rage and the English people imagine a vain thing, the Lord Jesus, who controls all events, is my friend, my master, my God, my all."
