539. In the spiritual world truth from good is the source of all power, and falsity from evil has no power whatever. This is because the Divine Itself in heaven is Divine good and Divine truth, and all power belongs to the Divine. Falsity from evil is powerless because truth from good is the source of all power, and in falsity from evil there is nothing of truth from good. Consequently in heaven there is all power, and none in hell; for everyone in heaven is in truths from good, and everyone in hell is in falsities from evil. For no one is admitted into heaven until he is in truths from good, neither is any one cast down into hell until he is in falsities from evil, (That this is so can be seen in the chapters treating of the first, second, and third states of man after death, Arcana Coelestia 491-520; and that all power belongs to truth from good can be seen in the chapter on the power of angels in heaven, 228-233)
