Selection from Arcana Coelestia ~ Emanuel Swedenborg
Suppose one of you has a hundred sheep and loses one of them. Doesn’t he leave the ninety-nine in the open country and go after the lost sheep until he finds it? And when he finds it, he joyfully puts it on his shoulders and goes home. Then he calls his friends and neighbors together and says, ‘Rejoice with me; I have found my lost sheep.’ I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent. Luke 15:4-7The angels, through whom the Lord leads and also protects a man, are near his head. It is their office to inspire charity and faith, and to observe in what direction the man's delights turn, and insofar as they can, without interfering with the man's freedom, moderate them and bend them to good. They are forbidden to act with violence and thus break the man's cupidities and principles; but are enjoined to act gently. It is also their office to rule the evil spirits who are from hell, which is done in innumerable ways, of which the following only may be mentioned. When the evil spirits pour in evils and falsities, the angels insinuate truths and goods, which, if not received, are nevertheless the means of tempering. Infernal spirits continually attack, and the angels protect; such is the order.
The angels especially regulate the affections, for these make the man's life, and also his freedom. The angels also observe whether any hells are open that were not open before, and from which there is influx with the man, which takes place when the man brings himself into any new evil. These hells the angels close so far as the man allows, and remove any spirits who attempt to emerge therefrom. They also disperse strange and new influxes that produce evil effects.
Especially do the angels call forth the goods and truths that are with a man, and set them in opposition to the evils and falsities which the evil spirits excite. Thus the man is in the midst, and does not perceive either the evil or the good; and being in the midst, he is in freedom to turn himself either to the one or to the other. By such means do angels from the Lord lead and protect a man, and this every moment, and every moment of a moment; for if the angels were to intermit their care for a single moment, the man would be precipitated into evil from which he could never afterward be brought out. These things the angels do from the love they have from the Lord, for they perceive nothing more delightful and happy than to remove evils from a man, and lead him to heaven. That this is a joy to them. Scarcely any man believes that the Lord takes such care of a man, and this continually from the first thread of his life to the last of it, and afterward to eternity.
