Hi & Salaam
Most replies were right .
To be messenger of God is a mission that needs many conditions , so , not any one can success in it , that means ,it is not good , at all , in thr right of God , to send a messenger , then he failed in his mission . So , God choses suitable persons for that mission that have many qualifies ,not found in other people .
Also ,God cannot be in direct touch with people , because he is unlimited being , so there must be a human being to be a mediator between God & people , those mediators are called messengers and prophets .
Imagine that you want a person to fulfil your mission , you will chose a suitable person who has all the needed qualifies to success in it , that's accepted matter and realestic .
In bible , it is said that Jonan escaped from this mission , and in the sea he was swallowed by a whale , in my opinion that doesnot give us a true view about the messenger , because messenger cannot refuse God's will to be his messenger , also messenger must not afraid from people , because he knowe well that he is protected from God .
These and other same things are the answer of the question , why God chose specific people for this mission .
I was astonished from the member who claimed that Adam & Eve were jews , i advice him to refer to the subject mentioned in this forum discussing that point .
