Excerpts from Arcana Coelestia ~ Emanuel Swedenborg
[N]o man has life from himself, and therefore neither can he think and will from  himself, for the life of man consists in thinking and willing. For there is one  only life, namely, that of the Lord, which flows into all, but is variously  received, and this according to the quality which a man has induced on his soul  by his life in the world. 
[E]veryone has life in accordance with the form of the interiors which he has  acquired by willing and acting, thinking and speaking. ...
[T]he influx of life from the Lord, that it flows into all, and that this is evident from heaven, in that heaven resembles a man, and is therefore called the Grand Man of which, and of the correspondence therewith of all things in man ...
[T]he universal heaven has reference to the Lord, and that the Lord is there the  center of all the looks, they who are in heaven looking upward to Him, and they  who are in hell looking downward from Him. For the Lord appears to those who are  in the heavens as a sun above them. ...
[T]he all of life is from the Lord from this fact also, that the soul of man can  in the womb so wonderfully form a body, and its manifold members and organs in  such a connection, and its interiors according to the image of heaven: this  could not possibly be done unless all life were from the Lord, and unless heaven were such as has been described. (Arcana Coelestia 6468)
Hence with the evil, goods and truths are turned into  evils and falsities; but with the good, goods are received as goods, and truths  as truths.
This may be compared to the light which flows into objects from the  sun, which is diversely modified and variegated in the objects in accordance  with the form of their parts, and hence is turned into colors either sorrowful  or gladsome, thus in accordance with the quality.
In like manner while a man  lives in this world, he induces on the purest substances that belong to his  interior a quality, according to which the Lord's life is received.
 Be it known  that the life from the Lord is the life of love toward the universal human  race.
(Arcana Coelestia 6467, 6468)
