Providing the most widely circulated book in the world is pretty good communicatuon. ~ Sea Breeze
But that fact that it is so confusing and contradictory that there is no singular accepted understanding of it (Wiki says there are over 33,000 differing "Christian" denominations) would indicate that it is a pretty bad attempt at communication.
Doesn't seem much better than those "must be assembled" instructions poorly translated into English by a factory worker in China.
Surely God could have done better, or at least provided an update (dare I say New Light?).
