It was 7 years before William Carey baptized his first convert in India; it was 7 years before Judson won his first disciple in Burma; Morrison toiled 7 years before the first Chinaman was brought to Christ; Moffat declares that he waited 7 years to see the first evident moving of the Holy Spirit upon his Bechuanas of Africa; Henry Richards wrought 7 years on the Congo before the first convert was gained at Banza Manteka. – A.J. Gordon, The Holy Spirit in Missions, pp.139-140
