"Inasmuch as the end of the creation is an angelic heaven out of the human race, and thus the human race itself, therefore all other things that are created are mediate ends, which being referable to man, look to these three things of man, his body, his rational part, and his spiritual part, for sake of conjunction with the Lord. For a man cannot be conjoined to the Lord unless he be spiritual; nor can he be spiritual unless he be rational; nor can he be rational unless his body is in a sound state. These things are like a house, of which the body is the foundation, and the rational is the house built upon it; the spiritual comprises those things which are in the house, and conjunction with the Lord is being at home in it." Here are outlined clearly and distinctly three fields for much needed labor. We see above, clearly taught by Swedenborg, that "a man cannot be spiritual unless he be rational, nor can he be rational unless his body be in a sound state." The reason is plain: for the natural corresponds to the spiritual; natural diseases and natural causes of disease correspond to spiritual diseases and spiritual causes of spiritual disease. Swedenborg says that: "Diseases correspond to the lusts and passions of the mind; these, therefore, are the origins of diseases; for the origins of diseases in general are intemperance, luxuries of various kinds, pleasures merely corporal; also envyings, hatreds, revenges, lasciviousness, and the like; which destroy the interiors of man, and when these are destroyed the exteriors suffer and draw man into diseases, and thereby into death."-- _Arcana Coelestia_, 5712. For this reason, if a man is to be reformed and regenerated, his reformation must commence by his shunning natural falses and bad habits of life, which correspond to his spiritual evils. Swedenborg's writings give us a wonderful insight into the causes and cure of both spiritual and natural diseases, as we shall hereafter see, and many suggestions which it would be well for us to heed. He says:-- "The man who is willing to be enlightened by the Lord, must take especial heed lest he appropriate to himself any doctrinal which patronizes evil; for man in such case appropriates it to himself, when he confirms it with himself, for thereby he makes it a principle of his faith, and still more so if he lives according to it. When this is the case, then evil remains inscribed on his soul and his heart; and when this effect has place, he cannot afterwards in any wise be enlightened by the Word from the Lord; for his whole mind is in the faith and in the love of his principle, and whatsoever is contrary to it, this he either does not see, or rejects, or falsifies." (A. C. 10,640.)
