How to Know God's Will by Watchman Nee. Watchman became a Christian in mainland China in 1920 at the age of seventeen and began writing in the same year. Throughout the nearly thirty years of his ministry, Watchman Nee was clearly manifested as a unique gift from the Lord to His Body for His move in this age. In 1952 he was imprisoned for his faith; he remained in prison until his death in 1972. His words remain an abundant source of spiritual revelation and supply to Christians throughout the world.
