Been there, I know this subject must be important to you or you would not have posted this twice. I can't guarantee that I will be able to watch/read all of those links you have provided.
I understand truth is important to being able to live our lives as effectively as possible...but understanding His TRUTH comes first and foremost.
Now having said that, I realize you may be a little like me and want the christian discussion to also include how it applies to our everyday lives. I have tried to do that but....
We have to be careful that all this truth seeking does not interfere with seeking the most important TRUTH out there. There are still many that need to be reached with the simple gospel...no matter how "milk of the word" it may be.
