Spiritually Speaking: If one argues that the Bible cannot prove itself

[I'm a nice person]

because it would be using circular? logic to say I believe the Bible because the Bible says it is true. Well; someone in my last question gave an answer that included this: " math and science prove themselves" so THEY cannot be proved. He was using this in context of answering a question on whether math and logic are based on empirical evidence. Do you think this is the same thing? I feel like this whole point is circular. But, is it? If you wish, you can see the answer in my other question.
