5979. A man who is in faith believes that none but angels from heaven are with him, and that diabolical spirits are altogether removed from him. But I can assert that in the case of a man who is in the concupiscences and delights of the love of self and of the world, and regards these as the end, diabolical spirits are so near him as to be in him, and to rule both his thoughts and his affections. Angels from heaven cannot possibly be within the sphere of such, but are without; and therefore the angels recede as the infernal spirits approach nearer. Nevertheless the angels from heaven in no case recede altogether from a man, for then all would be over with him, because if he should be without communication with heaven by means of angels, he could not live.
 That there are infernal spirits and heavenly angels with man is also in some measure taught by the doctrine of faith of Christian Churches; for this declares that all good is from God, and that evil is from the devil; and preachers confirm this by their prayers in the pulpit that God may direct their thoughts and their words, and by their saying that in justification all endeavors, even the least, are from God; and also that when a man lives well he suffers himself to be led by God; and likewise that angels are sent by God to minister to man. And on the other hand, when a man has committed any enormous evil, they say he has suffered himself to be led by the devil, and that such evil is from hell. They would also have said that spirits from hell were flowing into the interior evils which are of the will and the thought, if they had acknowledged these evils to be so great.
