The Word of God is self-authenticating. It doesn't need to be 'proved' from outside. 'Thy Word is Truth' (John 17.17).
Is it true that you take that on faith?
If I am to take the bible to be completely true, then I need faith .... that is what you are proposing, correct?
**Furthermore, the only reason I do not take the bible as completely true, is because I no longer have faith.
