Think of a computer, the hardware is fine, but somebody changed all of the programming so that 2+2=5. You go into your spreadsheet and everything looks odd. You check it using the calculator function and get the same answers. You fire up C++ and start looking at it that way. Same thing. Something may look a little off, but everything you use gives you the same answers.
The only way to find and fix the problem is to get outside the system.
JW's have the same problem. Their programming is set up to always return the answer "the WTBS is always right." No matter what they are looking at, doing, thinking, reading, it always comes back to "the WTBS is always right." Only when they are able to get outside the system can they find the flaws in their lives.
This is either a brilliant flash of light, or I need to go to bed.
