Book excerpt: In a time before youth were welcomed in short-term missions, Loren Cunningham founded Youth With A Mission to unlock the world for millions. He called young and old, women and men, and every ethnicity to go. Loren Cunningham's dream began with a vision - waves of young people from every nation going to every nation, telling everyone, everywhere about Jesus. How did God move Loren's dream from vision to reality and take him to every country on earth? Loren and his wife, Darlene, grew through tough lessons on hearing and obeying the Lord. This exciting story of Youth With A Mission shows how hearing God's voice is for every believer. Translated into 150+ languages, Is That Really You, God? is a practical guide to hearing God's voice and following His direction to change our hearts and our world. In this legacy edition, read a special new chapter On to Eternity, on "the biggest vision I can imagine" where Loren unveils his final call, to rally this generation to translate the Bible orally into every mother tongue on earth. In addition, see a special tribute called 'Grateful Reflections" on Loren's life from dear friend and senior YWAM leader David Joel Hamilton from his up close and personal experience serving Loren over the decades.
