Mankind has always looked for an understanding concerning the existence of things. They imagined divine powers bringing all those things a life or causing things.
The Divine Creator provided the greatest tool to learn what we should know, to make the best of our life, with His infallible Word, collected in 66 books, whereby 25% of the text is focussing on a Mashiach or Messiah, a Saviour for all mankind. For some people it may look an arcane language of ancient times not useful any more for our contemporary world. The written collection of order, instruction, or guide, issued by an authority much higher than any living being on this earth, may for many be not easily understood, abstruse or obscure, because they just not want to listen to the words like they are written down but prefer to listen to human doctrines which may confuse lots of people and bring a lot of false teachings into the world. The Bible is not at all arcane, requiring secret knowledge to be understood. One does not have to have a degree in theology to come to understand God's Word. To get to understand it and to get wisdom one needs to read it regularly and has to study those words given by the Most High, giving more attention to them than to words of so called theologians who prefer to hold on to human doctrines instead of Biblical doctrines.
