681. The nature of celestial and spiritual food can best be known in the other life. The life of angels and spirits is not sustained by any such food as there is in this world, but by "every word that proceedeth out of the mouth of the Lord" as the Lord teaches in Matthew 4:4. The truth is that the Lord alone is the life of all, and that from Him come all things both in general and in particular that angels and spirits think, say, and do, and also what evil spirits think, say, and do. The reason why these latter say and do evil things is that they so receive and pervert all the goods and truths that are of the Lord. Reception and affection are according to the form of the recipient. This may be compared to the various objects that receive the light of the sun, some of which turn the light received into unpleasing and disagreeable colors, while others turn it into pleasing and beautiful colors, according to the form, determination, and disposition of their parts. The whole heaven and the entire world of spirits thus live by everything that proceedeth out of the mouth of the Lord, and from this each individual has his life; and not only the whole heaven and the world of spirits, but also the whole human race. I know that these things will not be believed, nevertheless from the continuous experience of years I can assert that they are most true. Evil spirits in the world of spirits are not willing to believe that this is so; and therefore it has often been demonstrated to them-to the life-even until they have acknowledged with indignation that it is true. If angels, spirits, and men were deprived of this food they would expire in a moment.
