My take is that she may be just be offering pie in the sky here. I did not see where she made the connection that Africans were the people that God was making those promises to. That was Jewish writers version of what God promised them. The trouble with those promises is that they show God as looking the other way when Jews commit atrocities since He supposedly favored them. Muslims have some similar writings but with a slight twist. "Ye are the best of peoples, evolved for mankind, enjoining what is right, forbidding what is wrong, and believing in Allah." Qur'an 3:110 - For a Muslim to continue being "best" require that they continue "enjoining what is right and forbidding what is wrong as well as believing in Allah. Especially since there is another passage that promises to take away all the privileges God has given to Muslims if they stop being upright and give those blessings to another nation. There is proof of both of these scenarios happening for and to Muslims. There is also proof that the Jews wrote the books of the Bible and allotted those privileges to themselves. There is no proof that what this woman is saying about Africans being the people that God was speaking of in the Bible. Therefore she may just be misleading Africans with this argument. Perhaps there was another argument that would have worked better than this one.
