The New Testament is not written by Jesus, let alone God. It is not claimed by Christians to be from God either since obviously Matthew, Mark, Luke, John etc are not God.
The Torah and the Koran are believed to be the actual Word of God while the New Testament is only the word of mortal and fallible men testifying that they met an executed blasphemer Christians have been worshiping as the co-equal of the God of Israel who is also Allah for nearly 2000 years.
In an honest and rational world, the Word of God trumps the word of mortal and fallible men.
Even if we are not sure if God exists, that which is believed to be the Word of God should still trump the word of mortal and fallible men.
Even if all scripture claimed to be from God were in fact written by man, the one with the superior narrative and claim should trump the scripture of low status origins testifying to something that is morally and intellectually indefensible: that Jesus is the co-equal of the God of Israel who is also Allah.
Let's face it, if God exists, He would curse Christians for their blasphemy and also Jews and Muslims who have not in any way challenged the idolatry and blasphemy of Christianity. While Jews may be excused for not thinking it is their place to deny the divinity of Jesus which would amount to blasphemy in Christendom, what about Muslims in their own Muslim homelands?
