To Alexander Knox Date: LONDON, December 23, 1779. DEAR ALLECK, - The whole account of yourself which you still give convinces me more and more of what I have once and again observed concerning the nature of your disorder. It is undeniable (1) That you have a bodily complaint. Your nerves are greatly disordered; and although it is only now and then that this rises so high as to occasion a fit, yet it has a constant influence upon you so as to cause a dejection of spirits. This dejection is no more imputed to you as a sin than the flowing of the blood in your veins. (2) Although I will not say you have no faith, yet it is certain your faith is small; and you are fearful, because you are of little faith: this is another source of your uneasiness. (3) You want to have the love of God fully shed abroad in your heart: you have only now and then a little touch of thankfulness, a small spark of that divine fire; and hence anger, or at least fretfulness and peevishness, more or less, will naturally arise. Add to these (4) the main cause - diabolical agency. Satan will surely take occasion, from the situation you are in, to inject a thousand thoughts; and will then accuse you for them: but he, not you, shall answer for them to God. God is on your side: He knows whereof you are made; and Jesus careth for you. He keeps you and my dear Mrs. Knox as the apple of an eye; His Spirit helps your infirmities; He is purifying you in that furnace; and when you have been tried, you shall come forth as gold. Expect the blessing: is it not at hand - I am, my dear Alleck, Yours affectionately.
