For the first time after creating the world, God speaks to all mankind. This is the first book He publishes among mankind to expose, guide, chastise, and communicate with them. This is also the first utterance that makes known His footsteps, His resting place, His disposition, His possessions and being, His thoughts as well as His care for mankind. In other words, this is God’s first utterance from the third heaven. And it is the first time that God appears to mankind and expresses His heart through His word in His original identity.
