Born Muslims Have Unfair Advantage?
What you described above is a matter of mindset where one allows biases, prejudices, ego, arrogance, and other such human attributes get in the way of striving to find and accept the truth. What God really requires from the true believers is to rise above this mindset and accept or reject anything on the basis of merit. This is required for born Muslims as well as those who are born into other faiths. God has categorically stated His law of guidance in the Quran (short video below). Guidance and subsequently reward is granted to those who work in accordance with this law. To conclude, it’s the intention and the attitude towards truth that really counts. If a person with sincere intention makes a sincere effort to be guided, God has promised to help that person find guidance. Even still if that person arrives at the wrong conclusion, he will still find his reward with God on the day of judgement. The basis of salvation is not in the sticker label that reads “Muslim”, but in fact the attitude towards truth and falsehood, along with sincere intention and effort. I must add that this is a lifelong journey, not an event when one has finally received guidance and is now considered safe for life. https://youtu.be/4gDyxt4BonM
