The whole truth?

Katy and I enjoy a daily chapter of Ian Hamilton's, The Faith Shaped Life' at the breakfast table each morning. Today we read on p.113, 'When the Holy Spirit set about the work of infallibly inspiring men to pen God's saving revelation, he ensured that what they wrote was the truth, the whole truth and nothing but the truth.'
  I beg to slightly differ about the whole truth here. All written in the Bible is true and nothing but true but it is not the whole truth.  John 20:30 - Now Jesus did many other signs in the presence of the disciples, which are not written in this book; John 21:25 - Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written.   John did not give us the whole exhaustive truth about Jesus. The creation account does not tell us when God created nor the truth about the process. God does not satisfy our curiosity about the origin of evil in Satan. No. The secret things belong to God. Deuteronomy 29:29 - “The secret things belong to the LORD our God, but the things that are revealed belong to us and to our children forever, that we may do all the words of this law. So the Bible is not the whole truth. It is the truth God wants to reveal.
   The parallel is the court oath. The witness swears to tell the truth, the whole truth and nothing but the truth. But he is not free to tell any truth except in answer to questions from lawyers or judge. The whole truth is of no interest to the court. God's whole truth is hidden from us.
