This Volume by Geisler and Abdul Saleeb is substantial and covers all the aspects pertinent to the discussion ie.'Answering Islam'. Firstly, the contribution of Abdul is valuable as he was a former Muslim (who has converted to Christ) and his input gives credance to chapters 1 to 6 on the Basic doctrines of orthodox Islam as a first-hand source for the tenets. Secondly Geisler himself properly evaluates the Muslim views and preconceptions of divinity, revelation and prophethood and replies to the typical Muslim charges towards their Christian 'cousins' and being the fine apologist that he is, culiminates his Christian Response section with a defense of Salvation by the Cross. His approach is both sound and scholarly, with systematic & step-by-step assessments of the similarities and points of differences between Christianity and Islam. This Book will greatly benefit BOTH non-Christians and Christians alike who are interested in the subject and will certainly give them value for their money. The Appendices are comprehensive; throwing light on sectarian and cultic strands & interpretations of Islam, the 'gospel of Barnabas' and tracing its sources, showing it for the forgery that it is; and even not avoiding popular muslim accusations against the New Testament. Finally, theres a good Glossary section, an even better Bibliography (with Both Christian and non-christian Authors) and an excellent Suggested Reading section-for further research and study. ALL these are found in One Volume -what more can one ask for the layman as well as the specialist !
