Calvary Tribal Leadership Training (CTLT) provides Bible and ministry training to indigenous Christian leaders (many of whom are already pastors) on the island of Mindanao in the SE Asian nation of the Philippines. Research has shown that 80% of pastors in developing nations enter the ministry with no formal Bible School training. CTLT is changing that number in the Philippines by training Christian tribal leaders in towns near their mountain villages. This ministry is led by Rev. Ken & Rev. Cris Sandberg and their team of teachers who are alumni of Calvary Bible Institute in Davao City.
