Tsoukalas provides well-written, brief background and Christian evaluation of Nation of Islam, which most of us Americans hear much about and little understand.
He disbands the myths that it is Muslim. It differs as he carefully points out in its basic disagreement that W.D. Fard is Allah (God), and that he is a man, a black man. As anyone familiar with Islam is aware, this is totally against their view of Allah.
In a procession of messengers, beginning with Elihah Muhammed, continuing to Malcom X, then to Louis Farrakan, the author provides intro to this development and its implications.
Also, he provides advice on how a Christian can witness, given God provides the opportunity. This is very useful, as well as the accompanying discussion on a Christian evaluation of NOI. He is lacking on an understanding of the communication of Chrsit's two natures, which would alleviate the problems in this evaluation.
A good introductory read to the subject.
