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.
The Bible is not only the best sold book in the world, it is also the book which gives the best advice, but that is something man does not like to accept from Some One or Some Thing he cannot see or touch, though if man would be willing enough to hear and feel, he could feel the presence of the Most High and feel His Guidance. Until today lots of people have been rebellious against God and it is that rebellion which made it so difficult for mankind. When more people would follow the teachings of the Holy Scriptures we would have a much better world.
