And what proof would be enough for you? what evidence would be enough for you?
Psac, short answer: Probably the same proof that would be required for you to believe the Quran is inspired by the only true god.
Long answer: That's pretty open-ended but I'll throw you a bone. First of all, the Bible would need a huge makeover. It could not carry contradicting texts and descriptions of a self-refuting god. Let's cover some basic concepts.
- A perfect creator wouldn't be obsessed with being loved or worshiped as that, by definition, contradicts perfection since it represents a fundamental need on his part.
- There would also have to be some bridge between the gap of his superlative love and his willingness to let man suffer for the sake of his good name. (As a father, I hate to share my title with the Judeo-Christian god. Good parents don't drown their children.)
- This divine and uber-important message would have to transcend time and language barriers with NO CHANCE for loss of quality. Everyone would understand the message the same way, as there would be ZERO room for interpretation. Human language seems ill-fitted for such a task.
- ALL mankind could understand it without even learning to read and ALL mankind would have access to at ANY time.
- It wouldn't be transmitted in such a way that caused geographics partiality. Citizens of country X would not be at a disadvantage (because of isolation/environment) while citizens of country Y are taught it's message from birth.
- Evidence would be preserved for every single miracle (fairy tale). Since the "doubting Thomas" was supposedly allowed to demand evidence that he could test with his eyes and hands, the rest of us should have the right to expect the same evidence before we believe hearsay.
- There would have to be numerous examples that the bible writers had specific fore-knowledge that ONLY a creator of the universe might have. This would be conveyed in clear, unambiguous terms. Again, no room for interpretation and no self-fulfilling prophecy.
- It would be clearly established and verifiable by multiple independent, unbiased sources as to the date a prophecy was conceived and also verifiable by multiple independent, unbiased sources as to the date the prophecy was fulfilled. There would be ZERO room for debate on any prophecy.
- This wouldn't prove anything but it would've been nice to have this simple idea passed on at the very beginning: "Handwashing is one of the best ways to prevent the spread of infection and illness." For bonus points, he would've given us the scientific method in Genesis.
- The "commandments" would focus on compassion and love for fellow man instead of emphasizing devotion to a self-absorbed creator. These would also speak VERY CLEARLY against sexual or physical abuse of a child; rape; slavery; torture; kidnapping; or abuse of one's mate. (Too bad those weren't important enough to be mentioned, eh?)
- God's voice would be audibly heard each day by everyone and a verbal answer would confirm whether or not a prayer was being answered.
So much could be said but I guess that would be a good start...
