I have been on the mission field for more than 40 years. When I arrived in Colombia in 1972, the Orinoco-Amazon Basins held over 215 ethnic groups speaking 170 different languages.  The “New Tribes Mission” had been working in Colombia since the early 1940’s. One specific tribe, the Curripacos responded favorably to the gospel and numerous Baptist Indian Churches were established in the Jungles of Venezuela, Brazil and Colombia.
