FOR because that there be divers kinds of spirits, therefore it is needful to us discreet knowing of them; sith it so is that we be taught of the apostle saint John not to believe to all spirits.[278] For it might seem to some that are but little in conning, and namely of ghostly things, that each thought that soundeth in man's heart should be the speech of none other spirit but only of man's own spirit. And that it is not so, both belief and witness of holy scripture proveth apertly; for "I shall hear," saith the prophet David, "not what I speak myself, but what my Lord God speaketh in me";[279] and another prophet saith, that an angel spake in him.[280] And also we be taught in the psalm that the wicked spirits sendeth evil thoughts in to men; and over this, that there is a spirit of the flesh not good, the apostle Paul sheweth apertly, where he saith, that some men are full blown or inflate with the spirit of their flesh.[281] And also that there is the spirit of the world, he declareth plainly, where he maketh joy in God, not only for himself, but also for his disciples, that they had not taken that spirit of the world, but that that is sent of God, the which is the Holy Ghost.[282] And these two spirits of the flesh and also of the world are, as it were, servants or sergeants of that cursed spirit, the foul fiend of hell; so that the spirit of wickedness is lord of the spirit of the flesh, and also of the spirit of the world. And which of these three spirits that speaketh to our spirit, we should not believe them. For why, they speak never but that anon, by their speaking, they lead to the loss both of body and of soul. And which spirit it is that speaketh to our spirit, the speech of that same spirit that speaketh shall fully declare; for ever more the spirit of the flesh speaketh soft things and easy to the body; the spirit of the world vain things and covetise[283] of worship; and the spirit of malice of the fiend speaketh fell things and bitter.
