9. The Screwtape Letters by C.S. Lewis
This book could not be more perfectly timed as I just had a listening prayer time with a person where that person was hearing and believing a lot of lies from the enemy.
My favorite quote from p.59 in the 1977 version:
Screwtape clarifies the Enemy's intent:
"Of course I know that the Enemy also wants to detach men from themselves, but in a different way. Remember always, that He really likes the little vermin, and sets an absurd value on the distinctness of every one of them. When He talks of their losing their selves, He only means abandoning the clamour of self-will; once they have done that, He really gives them back all their personality, and boast (I am afraid, sincerely) that when they are wholly His they will be more themselves than ever. Hence, while He is delighted to see them sacrificing even their innocent wills to His, He hates to see them drifting away from their nature for any other reason. And we should always encourage them to do so."
