And of course, in the end, it's all a bit of circular reasoning on your part, isn't it? Why do you believe your assertions? They are in the bible. Why believe the bible? Because it's the inerrant word of god. How can you assert it is the inerrant word of god? Because it says so in the bible. Why believe the bible?....
Etc...etc...
Cant speak for anyone else, but I believe the Bible because God revealed it to me after a period of fasting and prayer to learn the truth. So I dont believe the Bible because it's the inerrant word of God. The Bible doesnt even say that. It makes no sense to pretend to claim the Bible says something when it doesnt.
There is no circular reasoning. Nor is there any indication that the Bible suggests it should be believed simply because it exists. Quite the opposite Christ told us that in order to know the doctrines were from God we needed to do them. It teaches us to seek God and find Him. Not blindly follow the Bible, but use the Bible as a tool to bring you closer to God and learn from Him.
What about people who harm their children because god revealed it to them? Is their belief less jusitfiable than yours?
I would easier believe that they were schizophrenic than believe God told them to do Harm.
I take that back to Genesis Chapter 1 Verse 1, just to make clear my position. When would Conscience Justify, unprovoked Attack or assault? Can you think of Anything?
