Mental Illness in the Bible

Madness or insanity is mentioned a number of times in Scripture, showing us that such things were present and well recognized in both the Old and New Testaments. We have already seen how the word “lunatic” is used in the New Testament to describe those who were afflicted with disordered thinking and behavior. There are many other references, however, in the Word of God. In the following verses, the word “mad” means a pattern of thinking or acting without reason or judgment.
In Deuteronomy 28:3434So that thou shalt be mad for the sight of thine eyes which thou shalt see. (Deuteronomy 28:34), Israel was told that they would be “mad for the sight of thine eyes” when they would see the awful judgments God would bring upon them for their disobedience. The word here has the thought of raving through insanity, clearly brought on by adverse circumstances.
In Daniel 4:1-371Nebuchadnezzar the king, unto all people, nations, and languages, that dwell in all the earth; Peace be multiplied unto you. 2I thought it good to show the signs and wonders that the high God hath wrought toward me. 3How great are his signs! and how mighty are his wonders! his kingdom is an everlasting kingdom, and his dominion is from generation to generation. 4I Nebuchadnezzar was at rest in mine house, and flourishing in my palace: 5I saw a dream which made me afraid, and the thoughts upon my bed and the visions of my head troubled me. 6Therefore made I a decree to bring in all the wise men of Babylon before me, that they might make known unto me the interpretation of the dream. 7Then came in the magicians, the astrologers, the Chaldeans, and the soothsayers: and I told the dream before them; but they did not make known unto me the interpretation thereof. 8But at the last Daniel came in before me, whose name was Belteshazzar, according to the name of my god, and in whom is the spirit of the holy gods: and before him I told the dream, saying, 9O Belteshazzar, master of the magicians, because I know that the spirit of the holy gods is in thee, and no secret troubleth thee, tell me the visions of my dream that I have seen, and the interpretation thereof. 10Thus were the visions of mine head in my bed; I saw, and behold a tree in the midst of the earth, and the height thereof was great. 11The tree grew, and was strong, and the height thereof reached unto heaven, and the sight thereof to the end of all the earth: 12The leaves thereof were fair, and the fruit thereof much, and in it was meat for all: the beasts of the field had shadow under it, and the fowls of the heaven dwelt in the boughs thereof, and all flesh was fed of it. 13I saw in the visions of my head upon my bed, and, behold, a watcher and an holy one came down from heaven; 14He cried aloud, and said thus, Hew down the tree, and cut off his branches, shake off his leaves, and scatter his fruit: let the beasts get away from under it, and the fowls from his branches: 15Nevertheless leave the stump of his roots in the earth, even with a band of iron and brass, in the tender grass of the field; and let it be wet with the dew of heaven, and let his portion be with the beasts in the grass of the earth: 16Let his heart be changed from man's, and let a beast's heart be given unto him; and let seven times pass over him. 17This matter is by the decree of the watchers, and the demand by the word of the holy ones: to the intent that the living may know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will, and setteth up over it the basest of men. 18This dream I king Nebuchadnezzar have seen. Now thou, O Belteshazzar, declare the interpretation thereof, forasmuch as all the wise men of my kingdom are not able to make known unto me the interpretation: but thou art able; for the spirit of the holy gods is in thee. 19Then Daniel, whose name was Belteshazzar, was astonied for one hour, and his thoughts troubled him. The king spake, and said, Belteshazzar, let not the dream, or the interpretation thereof, trouble thee. Belteshazzar answered and said, My lord, the dream be to them that hate thee, and the interpretation thereof to thine enemies. 20The tree that thou sawest, which grew, and was strong, whose height reached unto the heaven, and the sight thereof to all the earth; 21Whose leaves were fair, and the fruit thereof much, and in it was meat for all; under which the beasts of the field dwelt, and upon whose branches the fowls of the heaven had their habitation: 22It is thou, O king, that art grown and become strong: for thy greatness is grown, and reacheth unto heaven, and thy dominion to the end of the earth. 23And whereas the king saw a watcher and an holy one coming down from heaven, and saying, Hew the tree down, and destroy it; yet leave the stump of the roots thereof in the earth, even with a band of iron and brass, in the tender grass of the field; and let it be wet with the dew of heaven, and let his portion be with the beasts of the field, till seven times pass over him; 24This is the interpretation, O king, and this is the decree of the most High, which is come upon my lord the king: 25That they shall drive thee from men, and thy dwelling shall be with the beasts of the field, and they shall make thee to eat grass as oxen, and they shall wet thee with the dew of heaven, and seven times shall pass over thee, till thou know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will. 26And whereas they commanded to leave the stump of the tree roots; thy kingdom shall be sure unto thee, after that thou shalt have known that the heavens do rule. 27Wherefore, O king, let my counsel be acceptable unto thee, and break off thy sins by righteousness, and thine iniquities by showing mercy to the poor; if it may be a lengthening of thy tranquillity. 28All this came upon the king Nebuchadnezzar. 29At the end of twelve months he walked in the palace of the kingdom of Babylon. 30The king spake, and said, Is not this great Babylon, that I have built for the house of the kingdom by the might of my power, and for the honor of my majesty? 31While the word was in the king's mouth, there fell a voice from heaven, saying, O king Nebuchadnezzar, to thee it is spoken; The kingdom is departed from thee. 32And they shall drive thee from men, and thy dwelling shall be with the beasts of the field: they shall make thee to eat grass as oxen, and seven times shall pass over thee, until thou know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will. 33The same hour was the thing fulfilled upon Nebuchadnezzar: and he was driven from men, and did eat grass as oxen, and his body was wet with the dew of heaven, till his hairs were grown like eagles' feathers, and his nails like birds' claws. 34And at the end of the days I Nebuchadnezzar lifted up mine eyes unto heaven, and mine understanding returned unto me, and I blessed the most High, and I praised and honored him that liveth for ever, whose dominion is an everlasting dominion, and his kingdom is from generation to generation: 35And all the inhabitants of the earth are reputed as nothing: and he doeth according to his will in the army of heaven, and among the inhabitants of the earth: and none can stay his hand, or say unto him, What doest thou? 36At the same time my reason returned unto me; and for the glory of my kingdom, mine honor and brightness returned unto me; and my counsellors and my lords sought unto me; and I was established in my kingdom, and excellent majesty was added unto me. 37Now I Nebuchadnezzar praise and extol and honor the King of heaven, all whose works are truth, and his ways judgment: and those that walk in pride he is able to abase. (Daniel 4:1‑37), Nebuchadnezzar tells his nation how God humbled him with a severe mental illness for seven years until he learned a most important lesson, namely, that “the most High ruleth in the kingdom of men, and giveth it to whomsoever He will, and setteth up over it the basest of men” (Daniel 4:1717This matter is by the decree of the watchers, and the demand by the word of the holy ones: to the intent that the living may know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will, and setteth up over it the basest of men. (Daniel 4:17)).
In Acts 26:2424And as he thus spake for himself, Festus said with a loud voice, Paul, thou art beside thyself; much learning doth make thee mad. (Acts 26:24), Festus accused Paul of being mad. The word here has the thought of “mania,” or craziness. Paul replied that he was not mad, but rather was speaking the words of truth and soberness. Again, in 1 Corinthians 14:2323If therefore the whole church be come together into one place, and all speak with tongues, and there come in those that are unlearned, or unbelievers, will they not say that ye are mad? (1 Corinthians 14:23), Paul says that if unbelievers came into the assembly when the believers were speaking in tongues, they would think that they were mad, or raving like maniacs.
These references show us that insanity was clearly recognized for thousands of years. Sometimes it was brought on by circumstances, sometimes by demon possession, and sometimes by God Himself. The word “lunatic” is used once in the New Testament (Matthew 17:1515Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water. (Matthew 17:15)) to describe the state of one who was demon possessed, but in Matthew 4:2424And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them. (Matthew 4:24) a distinction is made between those possessed by demons and those who were lunatics. A disordered mental state might be caused by demon possession, but such a condition could occur in the absence of a demon. Thus we see that mental illness of various kinds and from different causes is recognized in the Word of God.
The Nature of Man
In considering mental illness, it is helpful to have an understanding of man and his nature, as given to us in the Word of God. However, since man is a complex being, some readers may find the subject complicated and the concepts difficult to grasp. For this reason, this section will be found in the Appendix. However, it may be turned to and read at this point, if desired.
