Tom Wallace is one of the foremost experts on Islam, it’s intentions toward the world and witnessing to Muslims about Christ. He is a missionary to Muslims and host of the excellent radio show Fortress of Faith with Shahram Hadian (Truth In Love Project), a former Muslim who is now a Christian. It can be heard on AFR Talk Saturdays at 12PM Central / 1PM Eastern. You can also download past episodes directly from the web site. In my opinion, it’s one of the best kept secrets on radio that every Pastor and every Christian needs to be listening to.
