The NT is the death and resurrection of Christ, why He came to earth, His
sole purpose for
living...
Now, this is obviously an extremely short description, and while others could have been more literate
in the description, I would suggest you go to any website for further clarification on why the NT was needed, prophesied, and Who it was all about... That is just a start... To be a «free - thinker» requires honest examination of both sides.
