Every Muslim people needed "first responders"...the vast majority of them never got in a book...Greatest Toil is THEIR story in Turkey, Iran, and the Arab World. This book is a love letter from an 80-year-old veteran of the Cross to his family in Christ Jesus, especially to Christ's ambassadors to the Muslim world. Muslims today are 24% of the men, women and children on the planet and are locked into Satan's masterpiece, "without hope and without God" (Eph. 2:12). These reflections, looking back on the faithfulness of the pioneering ground-breakers, is all about asking that question: OF WHAT IN THE PAST SHOULD WE BE AWARE? We pose this question so that the making of disciples of the Lord Jesus among followers of the false prophet can be done more fruitfully, i.e. "fruit that lasts" (John 15:16). These bits of mission history were envisioned to highlight efforts of the Lord's servants, up until 1978, across all the regions and nations of Turkey, Persia, Mesopotamia, and the Arab World. This present volume serves as only a small representative of the many more faithful servants of Christ, brothers and sisters who very likely heard "well done, good and faithful servant" on the day of their Homecoming. May these vignettes be utilized to cause fruitful reflection on the efforts of those who preceded us. It is hoped and prayed that you will be inspired by those who went before us, and that through the reflection questions you will be able to evaluate present ministries, avoid mistakes of the past, and be encouraged to experiment with what has not yet been attempted.
