Given that Islam is the true religion, what is the difference between a Muslim who was born into Islam and a non-Muslim who did not embrace it, even though the latter's destiny is Hell?

It is among a person's felicity and God's favor upon him to be born into a Muslim environment, so that he remains upon his primordial nature, otherwise his parents would Judaize him, or Christianize him, or Magianize him. Nevertheless, if a young person born of Jewish or Christian origin searches for the truth and believes in Muhammad, peace and blessings be upon him, he will have a great reward, and his faith will be stronger than one who inherited faith and did not search for the truth. God commanded the search for certainty and reproached disbelievers for imitating their forefathers. If a non-Muslim does not embrace Islam, his destiny is Hellfire, because he heard of the Prophet, peace and blessings be upon him, and did not believe in him. God has given humans insight to recognize the truth, and He has given them an excuse by granting them respite and sending messengers.
