God - a study in pointlessness.

[Subhan Ahmad]

What doesn't make sense to me is: Why is faith a requirement?
Why the need for a book?... specially a book that comes after other similar books already exist...

Brother imagine one thing. You go to your employer. Tell him to his face that you don't believe that he is your employer and you start doing your work against all the standard operating procedures. Do you think you will remain part of the company for long?

Faith is very important brother for any system to work. Tell me does any system works if you don't have confidence and trust on it?

You don't even get a software if you don't agree to the terms and agreements.
Can you even live in a country without abiding to its laws ?

Again tell me honestly if all this system does turn out to be true, do you really think a faithful and the unfaithful should be equal in front of God? If God does exits and treats both the believer and the unbeliever equally then this is a big injustice.

Quran says

"[Mention, O Muhammad], the Day We will call forth every people with their record [of deeds]. Then whoever is given his record in his right hand - those will read their records, and injustice will not be done to them, [even] as much as a thread [inside the date seed]." (17:71)

Why the need for a book?... specially a book that comes after other similar books already exist...

That is good that you realized the similarity. Since the beginning, human beings have been tested with the message that was essentially the same. And the message was conveyed through the prophet at the given time. Every time the prophet passed away and the true message got corrupted over the time, a new prophet came to restore the original message. But this chain of Prophets ended with Muhammad (peace be upon him). Why it ended? Because the message is well preserved in Quran and will remain preserved till the end of time.

Since the message was same, all the humanity faced and is facing the same test through different scenarios.

For me this makes totally sense that only one book is determining the rise and fall of individuals, societies and nations because:
1) There is only one Creator. One God means one message for whole humanity.
2) If there was even one more books then it would bring chaos. Two books mean two books with different dos and don'ts. Consider you and I follow different books. In your book drinking alcohol was allowed and in my it was prohibited. Do you think this makes sense?
3) All the dos and donts are actually whats good for us and what is not good for us. Like you get an instruction manual when you buy a machine. Think of two different instruction manuals for the same machine.
