All this has been happening around them all the days of their lives though they couldn’t see it, then one day, Prayer removes the veil and everything changes. Think of it this way: Picture a man whistling a tune, when out of nowhere, first a harmony joins, then another, and then suddenly he is taken up into a whirlwind of music, countless instruments playing soaring complexities that the man’s whistling is, indeed, a part of, but now he begins to see how small a part; the longer he listens, he realizes that his is not the melody and where he had thought he was whistling alone, the truth had always been the music playing, though never before that moment heard, and now what had been noise becomes symphony.

Also, always encourage 'being good' over 'doing good.' Acts of goodness are the difficulty for us and should, of course, be avoided. 'Being good' is far less problematic, largely because it lacks definition and can be solely a state of mind completely unattached to reality.

And keep them thinking in terms of 'being good' as this is not an end so much as a means to something else —happiness, respect, self-esteem, etc… And whatever their true end is, take it away, and so goes their goodness.

And once their imaginations are liberated, they begin glimpse the grand interconnectedness of all things. Eternity begins to peek out from behind the everyday things, and they see the trappings of any earthly moment as the stage and props for Heaven to reveal itself. There is now nothing ordinary. Everything is being used and spun out for His vast scheme and in His eternal economy, nothing is wasted. Suddenly, all the myriad moments and minutiae of a lifetime show their orchestration —there was nothing that did not lead to this! They look over all their time to find that His redemption has always been rushing, swooping, swerving through their experience, racing to and fro to intervene and infuse Grace.

And so, wish becomes pang; to crave, an ache; pleasure, pain. Losing all its pleasure, anticipation cuts the opposite direction and becomes merely a constant, painful reminder of what they’ve lost, forever.

An imagined pleasure is never really the pleasure, but an imagined pain, in a very real sense, is the pain, because so much of pain is the consciousness of it. It makes itself objective. Whereas to think about pleasure is to step outside of it; to think about a presently felt pain is to step inside it. And in a very real sense, we’ve already got them in Hell.

As a motivation —for humans, but Christians especially— guilt is always wrong and can never move them to do anything He wants of them. Never let them realize that.

As a rule, Americans are big on that word “choice” and some souls can be captured simply by dangling before the creature a continual, lifelong supply of things from which to choose.

At the same time, they find their mind-god has played a trick on them. For mind is a part of the very system it has closed around it, and being inside, there is no reason to think any statement made by some part concerning the whole has any validity. Mind was caused by the material universe, if mind is right. But only the greater can accurately define the lesser, never the other way round, so if mind is right, mind would never know.

But here I’d like to add to what the Tempter’s Manual suggests. Depression, at its finest, is not a Future that they cannot hopefully construct, nor a shamed Past that hounds them, but an agonizing Present that they cannot escape. We want to disable their Present so that they cannot use it to look Heavenward.
