text: If there is one God and savior how do you know it is your God that is the one true God and not Vishnu or Loki or Horus, or any of the other myriad gods throughout the ages? Because the bible tells you so? A book written by man? 
  
  In the history of man kind and our religions, Christianity is a quite young religion. Building on the idea of one true God you put forth, why, then did this one true God take so long to emerge and why, then, have there been and still are so many different religions? One would assume that if there is a singular true creator that religion and worship would be universal and immutable - a single right answer, if you will, much like 2 + 2 always equals 4 regardless of culture or beliefs or language.
