Diversity is beautiful, in fact Islam encourage it, Quran(49:13):"O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things)."
Muslim pray shoulders to shoulders 5 times a day, the rich and poor, the white, black, Asian, and all races. We do not have a mosque for white and another for black or Chinese or Indian, we all pray in one masque regardless of race. There is one difference between all of us, and only Allah knows that difference, so it should not effect this unity.The prophet peace be upon him said "There is no honor for a white man over a black man, or for an Arab over a non-Arab except in piety" Islam teaches us how be united in a diverse community.
In regards to diversity in religion and the article I totally disagree I only agree with one part of it, that GOD is not Christian, in fact GOD is not Muslim too. Islam mean submission, which means the submission of the son of Adam to the rules of GOD.
If we believe that there is a creator, regardless of one's faith we all believe in a creator, different religion call him different names but we agree on the concept even if our methods are different.
This creator will want us to worship in a certain way, we believe if he want us all believe in him he could make us but he created Angels without desires to worship him, and he created human with desires and showed him the way, and is up to him to chose the path but at the end there is judgment day and hell or heaven.
Diversity in religion will not be accepted by Allah. For example if you work in a company, and you have been given guidelines how to carry out your job but you decided to ignore the guidelines, and did the job the way you feel like it. You go to work once a week or not go at all, where as others, go to work every day, and submit their daily tasks five times a day no fail, follow the guidelines to the letter. They miss all the fun you are having, while skipping work.
At the end of the year, all the staff are up for a review, some might lose their jobs and some might even get a bonus. Do you think it is fair to give bonuses to those who applied their rules that suit them?? Or worse they are equal to those who did the job to the best of their ability?? If we don’t think that is fair treatment in a place of work why would we accept that to be fair from GOD???
I am not saying this religion is right and the other is wrong BUT I don’t feel it is fair that GOD will accept all religions, regardless of who did his home work in this life, either by searching the truth or applying what he learned about the creator to the best of his knowledge.
If we believe that Allah (GOD) will accept all religion then why Muslim restricts themselves??if all will lead to the same destiny. We might as well have fun like other religions, and in the Day of Judgment we will say to GOD heaven please?
"If anyone desires a religion other than Islam (submission to Allah (God) never will It be accepted of Him" 3:85
