If you are a rational person with no preconceived notions how do you distinguish the Bible from the Koran based on self-attestation? Self-attestation means we have to believe every book and person who 'claims' to be written/inspired/breathed etc etc by God. How in the world is self-attestation useful?
It is not the only method of proof. I recommended Wayne Grudem's article, "Scripture's self-attestation and the problem of formulating a doctrine of Scripture", in D A Carson & John D Woodbridge (ed),
Scripture and Truth. Grand Rapids, Michigan: Baker Books, 1983, 1992. it was to determine the doctrine of the Christian Scriptures.
You have falsely made some assumptions about what I wrote, that we have to believe the claims of every book and person that claims to be inspired. That's not what I said and it is an illogical extension of what I said. That is not what I wrote nor what I intended.
When we compare the Qur'an and the Bible, there are other factors to consider, including:
(1) The contrast between the nature of Jesus Christ and the nature of Mohammed.
(2) The doctrine of Yahweh God vs the doctrine of Allah. One is trinitarian and the other unitarian. There are other attributes that differ.
(3) The content of the alleged Scriptures. One example is Mohammed's revelation of Jesus Christ. Is it accurate when assessed by the Christian Scriptures?
(4) The date of Islamic revelation vs the date of OT and NT revelation.
Take a look at this contrast:
Quran Jesus not crucified (4:157-159). Bible Was crucified (Lk. 23:33).
The Quran, sura 4:157-159[1]
157. And because of their saying: We slew the Messiah, Jesus son of Mary, Allah's messenger - they slew him not nor crucified him, but it appeared so unto them; and lo! those who disagree concerning it are in doubt thereof; they have no knowledge thereof save pursuit of a conjecture; they slew him not for certain.
158. But Allah took him up unto Himself. Allah was ever Mighty, Wise.
159. There is not one of the People of the Scripture but will believe in him before his death, and on the Day of Resurrection he will be a witness against them
The Bible, Luke 23:33
"When they came to the place called the Skull, they crucified him there, along with the criminalsone on his right, the other on his left" (NIV)
When one revelation contradicts the content of the other's revelation, we have a major issue with the accuracy and integrity of the Qur'an.
