I do not accept the Quran. By your own reasoning, the Quran was compiled through human hands the same as the bible. Muhammad was illiterate, as I understand, and his wife and followers put the Quran together based on his revelations. The same as Jesus's disciples testified to Jesus as the Mesiah and Son of God, and how his disciples and disciples disciples recorded the teaching of Jesus Christ.
I accept the truths of the Bible, and the teachings of Jesus Christ. I believe God is all powerful, and has preserved the teaching of Jesus throughout the years in the form of the Bible.
I understand Muslims believe that the bible has become corrupted from translation. However, I believe that God has used the Holy Catholic Church, and the lineage of Peter, to preserve those works. I fail to accept that God was unable to keep his word intact, as you believe.
