We do that every where we go. We speak to others about our Christian faith. St Paul said, 'for I am not ashamed of the gospel...' Here Sophie is talking about salvation in Jesus Christ. There is still so much work to be done. I remember James Hudson Taylor who went to China and endured all kinds of hardships and eventually the China Inland Mission was started and travelers like Mildred Cable lived in the interior of China for twenty years preaching the gospel. The American missionary, Marion Gribenow lived and preached in Labrang for years. Though not much if anything at all is left of their work, still they persevered.
