Add to that countless other types of progression and the possibilities become infinite. All this, however, is still in the natural order, and reading it can soon become a 'weariness of the flesh'. But it points to something much greater. Infinite levels of spiritual truth are also hidden in the scriptures. Jesus told his disciples that one of the functions of the Holy Spirit was to lead them into all truth.
Revealing truth hidden in scripture is a part of that great work.
So when God wrote his book he sealed it with seven seals and gave the power to open them to his son Jesus. Through the ages to come he will break those seals one by one, and reveal vast vistas of spiritual truth to his people. Michael Drosnin's book is a sign that God through Jesus will reveal much deep and wonderful spiritual truth that is hidden in the scriptures to those who have eyes to see and ears to hear. Ivan Panin discovered numeric patterns in both Old and New Testaments which also place God's seal on the scriptures. See also David and Solomon for related material.
