"As missionary teams multiplied across Muslim Southeast Asia in the late 1980s and early 1990s, veteran church planter Roger Dixon began investing in newer personnel. Climbing Higher includes 100 of his invaluable letters of encouragement. It's been called a My Utmost for His Highest for cross-cultural workers. While theorists multiply, successful church planters in the Muslim world remain few. Roger is one who, by God's grace and through much prayer, has played an instrumental role in the birthing of dozens of churches. Climbing Higher reflects some of his experiences and speaks to the nature of life among an unreached people group."--Summary from Pioneers website
