Another milestone in the history of Jehovah’s people was reached in 1935 when, at the Washington, D.C., convention, the “great crowd” of Revelation 7 was positively identified as an earthly class to be gathered before Armageddon. This new understanding served as a stimulus to greater activity, and the records show a steady increase in praisers of Jehovah in Jamaica. The number rose from 100 in 1914 to 390 in 1938, and by 1939 those inviting others to join them in becoming praisers of Jehovah reached 543.
