History of reaching

Reaching the coastlands - William Carey - 1792 - An "under thirty" young man, William Carey, got into trouble when he began to take the Great Commission seriously.

Reaching inland - Hudson Taylor - 1865 - A second symbolic event of 1865 is even more significant— at least for the inauguration of the Second Era. A young man, after a short term and like Carey still under thirty, in the teeth of surrounding counter advice, established the first of a whole new breed of missions emphasizing the inland territories.

Reaching the unreached - Donald McGavran - 1935 - At the very same time that Townsend was ruminating in Guatemala, Donald McGavran was beginning to yield to the seriousness, not of linguistic barriers, but of India’s amazing social barriers. Townsend "discovered" the tribes; McGavran discovered a nearly universal category, which he labeled "homogeneous units," which today are more often called "people groups."
