I understand where he is coming from, even though I don't take it as far as he takes it.
Belief in "The Bible" is not mandatory for Salvation. Belief in Christ and his resurrection are. "If thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the Dead, thou shalt be saved."
We should stop focusing on proving a 6 day creation, Jonah and the Whale, or Noah's Ark (sorry Ark Encounter...) In essence, we should not make "belief in the Bible" the cornerstone of our interactions with the World. I believe that "All Scripture is given by inspiration of God" but that message is rejected by most unbelievers.
What they can't disprove is that Jesus lived, was crucified, and was resurrected. No body was ever found. No apostle ever recanted his appearances even under threat of death. In Paul's day, many witnesses to the resurrection were around.
Many people reject Christianity because they don't think that Adam rode a dinosaur or that Eve was tricked by a talking snake. We tell them that if they don't believe in a Worldwide Flood, a 965 year old man, or the Exodus from Egypt, then they can't' be saved.
Faith in Christ (and his resurection) along with the influence of the Holy Spirit will lead people to become Bible Beleivers. Don't spend your time arguing "the Bible" with unbelievers, focus on Christ and him crucified.
