God is not 'an entitly who shows particular interest and favouritism towards one middle-eastern tribe', He is the only God (see Exodus 20 3-6) and he has an interest in every human being, all 6billion of us, on this planet, as he has throughout the ages.
Well, you have to admit that he does seem to have chosen all his prophets from one tribe when there were people spread out over six continents. And when he comes to earth as his own son, guess which tribe he appears amongst.
Wouldn't it be a bit more convincing if He had sent his word to a number of different characters from different cultures all over the world? More practical, as well, because the natives of the Americas and Australia, for example, wouldn't have had to wait until the Europeans arrived to take over their land before they could have a chance to be saved.
