You already proved the point when you said a person can't be saved except but hearing and hearing by the word of God. What made you believe in the Bible? walking on water? the talking snake?
Behold, the LORD's hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: Isa 59:1
I know if it wasn't his hand that held me by the back of the neck and pushed my face into the scriptures, I would have never done it voluntarily.
