The central theoretical argument of this book is that all humans ought to worship and serve the almighty God, their Creator and Maker of heaven and earth in the light of the Scripture. Humans ought to worship God in spirit and in truth. All human beings as God's creation in His image have no rights to worship other gods other than the almighty God. More so, man's genuine spirituality is dependent on the Spirit of God and the Word of God. The fact that God is the ultimate Giver of life and He rules over all things obligates everyone to worship and serve Him alone.
