This part is one of the least researched parts I've encountered, the thought that Mr. Docterman has put into it is extremely small. He says that if God was truly all-knowing He would have just put the knowledge of Him into our own brains himself instead of composing an "indecipherable amalgam of books which is the Bible as a means for avoiding the hell which he has prepared for us. The perfect God has decided to reveal his wishes in this imperfect work, written in the imperfect language of imperfect man, translated, copied, interpreted, voted on, and related by imperfect man," to use its own words.
For one thing, it figures that it would call the Bible an indecipherable amalgam. The thing is, we all bring our own predetermined beliefs to it whenever we read the Bible, which leads to some wrongful interpretations. The Bible was written more than 1000 years ago, so it just makes sense for you to have to look back at the phrases and symbols that would have made perfect sense to people then. The historical context is of utmost importance when you are studying scripture, a point with Chad Docterman obviously overlooked.
While it is true that it takes more than one lifetime to fully understand the entire Bible, understanding every bit of it isn't necessary. I cringe a little at using the word necessary because every Christian should attempt to spend time in the Word every day, but what I'm saying is that the reason God hasn't revealed His nature to us individually and completely is because He wants to see people seeking after Him, and one of the ways Christians do that is through reading the Bible to find out more about their faith. Not every sentence in necessary to salvation, but it does give more insight into the true nature of our Heavenly Father.
