1. Emphasis on eternal hell.
Generally the Bible dichotomizes Eternal Life as opposed to Destruction/Perishing, and only rarely as opposed to Eternal Punishment. And I don’t think there’s ever clarity that the individual is eternally present & conscious amidst torture. The worm does not die, the fire is not quenched… but worms and fires eat and burn up people, and then the people are gone. REFERENCES?
Hell as a place for punishing an individual eternally seems to be a much more prominent feature of the Qur’an (at least in the first surah or two that I’m reading… obviously not a scholar on the topic!)
However, the latter view is (in my subjective experience) generally the main / orthodox view amongst conservative / evangelical Christianity.
2. Emphasis on the ENTIRE scripture as straight from God’s mouth and utterly authoritative.
The entire Qur’an (I think) claims spoken from God’s perspective, to Muhammad, for immediate/direct line-by-line application to every area of life. Given pristinely, 100% authoritative / true.
Whereas in the Bible you’ve got swaths of history with varying appearance of historicity / symbolism, referenced and emphasized in alternatingly high and low emphasis by Jesus (never quoting Joshua, for example), authors appearing to debate each other within both NT (law/gospel) and also OT (good happens to the good / bad happens to the good), sexy love poems that never mention God, etc. Jesus actively transgressing on previously declared law codes, etc.
Again, it seems to me that evangelicalism/orthodoxy sees the Bible more like the Qur’an sees itself than like the Bible sees itself.
Something the New Testament and the Qur’an actually do share outright: Respect & homage for previous tradition.
I had heard that the Qur’an had some validations for Christianity and Judaism, but I didn’t imagine they’d be so densely packed within the text! The Qur’an affirms that Christianity’s and Judaism’s God is THE God just about as thoroughly as the N.T. affirms that Judaism’s and Christianity’s God is THE God. (A lot!)
(DISCLAIMER: I’ve read through the whole Bible but once, and largely when sleepy. I’ve read about 1 Surah (//book) of the Qur’an so far. Count me as authoritative AT YOUR OWN PERIL.)
