Baker worked for years with little fruit and he almost gave up, until the Holy Spirit came with power, but he never put the spiritual above the Word and searched the Scriptures to make sure what was happening agreed with the Bible. This is reflected in his books as he includes Scripture references in most chapters.
Harold Armstrong Baker (1881–1971) was an American author and missionary to Tibet from 1911 to 1919; then to China from 1919 to 1950 when he and his wife, Josephine, were forced to leave the mainland; then to Taiwan from 1955 until his death in 1971.
