It was a stormy night in Birmingham, England, and Hudson Taylor was to speak at a meeting at the Severn Street schoolroom. His hostess assured him that nobody would attend on such a stormy night, but Taylor insisted on going, saying,
I must go even if there is no one but the doorkeeper.
Less than a dozen people showed up, but the meeting was marked with unusual spiritual power.
Half of those present either became missionaries or gave their children as missionaries; and the rest were faithful supporters of the China Inland Mission for years to come.
