Roger S. Greenway has compiled and edited ten of Zwemer's best chapters, all taken from books long out of print, and has added an introduction providing an overview of Zwemer's life and work.Because his insights are not dated, writes Greenway, Zwemer needs to be heard again. Islam and the Cross makes available some of Zwemer's insights regarding Islam, the basic differences between Islam and Christianity, and a sense of love for Muslim people and a passion for their salvation.
