● The Quran's chapters are ordered from longest to shortest, not chronologically. Chronologically, the Quran's peaceful verses occur before Muhammad gains power whereas the calls to jihad (war on unbelievers) occur after Muhammad gains power. Apparently, the later verses abrogate the earlier verses. (Reading assignment: Yoel Natan, "164 Jihad Verses in the Koran," Answering Islam.)
● The Bible's calls to war are specific and limited to particular times and places, but the Quran’s call for jihad is open-ended.
