Not sure if there was a thread like this before, but...
There are times that certain books touch us in our spirtual lives, sometimes in an emotional way, other times in a theocratical way.
The Shack by William Young touched me deeply and renewed my faith in Jesus and God.
In Search of Christain Freedom and Crisis of Conscience by Raymond Franz, made me aware that the issues I laways had with organized religion were not just mine.
Question of COnsceince by Charles Davis, showed me the the issues that Mr.Franz faced in the WT were faced by other in the RCC far earlier and made me understand that we must truly server Christ and NOT any man-made organization.
The Jesus I Never Knew by Philip Yancey, which I read after The Shack motivate dme to read the NT with new eyes.
The NRSV of the NT with greek Interlinear, One of the best study interlinears I have.
The Oxford Bible commentary, a must for any student of the bible.
