NOTE: Teaching English (both formally and informally) is perhaps not only the most effective evangelism tool, but is also currently THE most requested ministry tool from all our ministry locations, especially from our Cambodian churches and ministry contacts.
Some ministries have everything ready for you to teach English, many do not. So please be prepared to do an English camp or teach English at local schools and universities, or in slums, or at churches. Please also be prepared for a variation in age groups and English skill levels. (The more creative and fun the better!)
