You see, as I told you earlier, I believe there is a God/ Super Consciousness/ Creator. Religion/belief system gives a sense of purpose, comfort & solace to many of their believers. For instance, a Native American may believe that trees have Spirits & He has to respect them, Why should I have a problem with that? On the other hand, I’m sceptical when religions especially Abrahamic one claim monopoly of truth, wisdom & morality and declare their myths as facts & the myth of others as fables. Let me put it in perspective, I‘m thankful that I have a great & blissful life. I enjoy every moment of it and am comfortable in the culture I was born in. Recently a Christian acquaintance spoke to me about Jesus being the only true God/Saviour etc & gave me some reading material. It was an interesting read but nothing moved me or blew my mind away that compelled me go to the extent to convert, though I had the freedom. Now I should burn in Hell for eternity for my friend’s failure to convince me to accept Christ? What's my fault, does it makes fair sense?
As for your claim that Quran’s divinity is proven beyond doubt, it’s just a claim & the burden of prove is on you.
Now, just reading the above few posts, I can see Muslims can’t come to an agreement on free will and/or predestination. From what I've learnt thus far from other sources, there is no real free will in Islam. Even your "evil" act is pre-ordained for you & shall rot in Hell eternally for it. Again does it make fair sense?
