For Muslims, Quran survives only in words and sentences printed in the Book. For example, if two groups of Muslims are at each other’s throat on sectarian issues, can we tell them that Quran forbids sectarianism, so stop it. Does it work? Did it work?
You say ‘Accept the way of life described in the Quran and you will solve all problems’ remains only in the valley of its sayings, nothing practically coming out of it. People generally are more motivated by their own passions than Quranic reasoning, so the issue is human awakening.
