The world is filled with human toxins -- not the darkness that we all occasionally crave, but actually people who are so unwilling to bask in the angelic light that is offered us all that they grow poisonous -- and you can pray for their eventual recovery and healing. And sometimes those prayers will be answered. But sometimes these individuals have been vaccinated against goodness and against angels and they are so unwilling to give an inch to their God that often they never (and I use this expression absolutely literally) see the light.
