David Brookins

“The Enemy takes this risk because He has a curious fantasy of making all these disgusting little human vermin into what He calls His ‘free’ lovers and servants—’sons’ is the word He uses, with His inveterate love of degrading the whole spiritual world by unnatural liaisons with the two-legged animals. Desiring their freedom, He therefore refuses to carry them, by their mere affections and habits, to any of the goals which He sets before them: He leaves them to ‘do it on their own’. And there lies our opportunity. But also, remember there lies our danger. If once they get through this initial dryness successfully, they become much less dependent on emotion and therefore much harder to tempt.”
