Charles H. Spurgeon on Psalms 119:70

Their heart is as fat as grease; but I delight in thy law; as if he should say, My heart is a lean heart, a hungry heart, my soul loveth and rejoiceth in thy word. I have nothing else to fill it but thy word, and the comforts I have from it; but their hearts are fat hearts: fat with the world, fat with lust: they hate the word. As a full stomach loatheth meat and cannot digest it; so wicked men hate the word, it will not go down with them, it will not gratify their lusts. William Fenner.

Being anxious to know the medical significance of fatty heart, I applied to an eminent gentleman who is well known as having been President of the College of Physicians. His reply shows that the language is rather figurative than literal. He kindly replied to me as follows:

There are two forms of so called "fatty heart". In the one there is an excessive amount of fatty tissue covering the exterior of the organ, especially about the base. This may be observed in all cases where the body of the animal is throughout over fat, as in animals fattened for slaughter. It does not necessarily interfere with the action of the heart, and may not be of much importance in a medical point of view. The second form is, however, a much more serious condition. In this, the muscular structure of the heart, on which its all important function, as the central propelling power, depends, undergoes a degenerative change, by which the contractile fibres of the muscles are converted into a structure having none of the properties of the natural fibres, and in which are found a number of fatty, oily globules, which can be readily seen by means of the microscope. This condition, if at all extensive, renders the action of the heart feeble and irregular, and is very perilous, not infrequently causing sudden death. It is found in connection with a general unhealthy condition of system, and is evidence of general mal-nutrition. It is brought about by an indolent, luxurious mode of living, or, at all events, by neglect of bodily exercise and those hygienic rules which are essential for healthy nutrition. It cannot, however, be said to be incompatible with mental rigour, and certainly is not necessarily associated with stupidity. But the heart, in this form of disease, is literally, "greasy", and may be truly described as "fat as grease." So much for physiology and pathology. May I venture on the sacred territory of biblical exegesis without risking the charge of fatuousness. Is not the Psalmist contrasting those who lead an animal, self indulgent, vicious life, by which body and mind are incapacitated for their proper uses, and those who can run in the way of God's commandments, delight to do his will, and meditate on his precepts? Sloth, fatness and stupidity, versus activity, firm muscles, and mental rigour. Body versus mind. Man become as a beast versus man retaining the image of God. Sir James Risdon Bennett, 1881.
