The books "Crisis of conscience" and "In search of Christian Freedom" did a lot in bidding the JW religious organization bye.
A challenge to refute the book was an exercise in futility.
After completely digesting the materials personally with a lot of note taking. I ensure I was able to see the practical benefits of the book for another two to three years within the set up of Jehovah's religious organization before exiting.
@ disillusioned you will find CoC and ISCoF really interesting to read. The moniker used by a person on a public forum led me to CoC, I discovered he wrote the second one ISCoF while reading CoC book. Immediately I completed CoC, I read ISCoF.
I tend to like the title of all the chapters of these books. It is after reading you will appreciate why these chapters are coined that way.
