“It is clear that there must be difficulties for us in a revelation such as the Bible. If  someone were to hand me a book that was as simple to me as the multiplication  table, and say, 'This is the Word of God. In it He has revealed His whole will and  wisdom,' I would shake my head and say, 'I cannot believe it; that is too easy to be  a perfect revelation of infinite wisdom.'
There must be, in any complete revelation of God's mind and will and character  and being, things hard for the beginner to understand; and the wisest and best of  us are but beginners.”
~  R.A. Torrey
