This is a little bit of a longer one. I didn't want to leave out some of the details Lorenzo Dow wrote about.

One of the things I love about this testimony was this sense Dow had that the people he sought advice from “seemed to be like physicians that did not understand the nature of my disorder.” The platitudes of modern Christianity are like giving Tylenol to a cancer patient when what they need is the cure. What I need is a cure for my “bent to sinning,” not a “well, God loves you.” 

Thanks be to God that he not only gives what we ask for, but he delights to do so.

As background, Lorenzo Dow was an itinerant Methodist preacher in the early 19th century. That's a bit of an understatement, but you can read more about him here (affiliate link). According to wikipedia, his autobiography was once the best-selling book in America apart from the Bible.

"When I was on the Orange (Connecticut) Circuit," says he, "I felt something within that needed to be done away. I spake to one and another concerning the pain I felt in my happiest moments, which caused a burden but not guilt; some said one thing and some another; but none spoke to my case, but seemed to be like physicians that did not understand the nature of my disorder; thus the burden continued, and sometimes felt greater than the burden of guilt for justification, until I fell in with T. Dewey, on Cambridge Circuit. He told me about Calvin Wooster, in Upper Canada, that he enjoyed the blessing of sanctification, and had a miracle wrought in his body, in some sense; the course of nature turned in consequence, and he was much owned and blessed of God in his ministerial labors. I felt a great desire arise in my heart to see the man, if it might be consistent with the Divine will; and not long after I heard he was passing through the circuit and going home to die. I immediately rode five miles to the house; but found he was gone another five miles further. I went into the room where he was asleep; he appeared to be more like one from the eternal world, than like one of my fellow mortals. I told him, when he awoke, who I was and what I had come for. Said he: ‘God has convicted you for the blessing of sanctification, and that blessing is to be obtained by the single act of faith, the same as the blessing of justification.’ I persuaded him to tarry in the neighborhood a few days; and a couple of evenings after the above, after I had done speaking one evening, he spake, or rather whispered out an exhortation, as his voice was so broken, in consequence of praying, in the stir of the Upper Canada, as from twenty to thirty were frequently blessed at a meeting. He told me that if he could get a sinner under conviction, crying for mercy, they would kneel down a dozen of them, and not rise until he found peace; for, said he, we did believe that God would bless him, and it was according to our faith.

"At this time he was in a consumption, and a few weeks after expired; and his last words were, as I am informed, ‘Ye must be sanctified or be damned,' and casting a look upwards, went out like the snuff of a candle, without terror; and while whispering out the above exhortation, the power which attended the same, reached the hearts of the people; and some who were standing or sitting, fell like men shot in the field of battle; and I felt a tremor to run through my soul and every vein, so that it took away my limb power, so that I fell to the floor, and by faith, saw a greater blessing than I had hitherto experienced, or in other words, felt a Divine conviction of the need of a deeper work of grace in my soul; feeling some of the remains of the evil nature, the effect of Adam's fall, still remaining, and it my privilege to have it eradicated or done away; my soul was in an agony-I could but groan out my desire to God-He came to me, and said, believe the blessing is now; no sooner had the words dropped from his lips, than I strove to believe the blessing mine now, with all the powers of my soul, then the burden dropped or fell from my heart, and a solid joy, and a gentle running peace filled my soul.

"From that time to this I have not had the ecstacy of joy or that downcast of spirit as formerly; but more of an inward, simple, sweet running peace from day to day, so that prosperity or adversity doth not produce the ups and downs as formerly; but my soul is more like the ocean, whilst the surface is uneven by reason of the boisterous wind, the bottom is still calm; so that a man may be in the midst of outward difficulties, and yet the center of the soul may be stayed on God; the perfections of angels are such, that they cannot fall away; which some think is attainable by mortals here; but I think we cannot be perfect as God, for absolute perfection belongs to Him alone; neither as perfect as angels, nor even as Adam before he fell, because our bodies are now mortal, and tend to clog the mind, and weigh the spirit down; nevertheless, I do believe, that a man may drink in the Spirit of God, so far as to live without committing wilful, or known, or malicious sins against God, but to have love the ruling principle within, and what we say or do to flow from that Divine principle of love and not from a sense of duty, though subject to trials, temptations, and mistakes at the same time."
