this should not be treated as usual book as it isn't ,it explains the long relation between man &god with man s mistakes and god forgiveness in sometimes &punishment in other-times over ages ,and how god descended to earth in human form to bear the punishment of man kind to make Justice &in the same time to liberate and forgive human race from the original sin.it contains endless amount of historical spiritual events &examples that can be applied on our own life regardless the changes between the today life &the the life in the past, so i find it very useful to .
