WEC began work in 1947 with four missionaries, and since then there has been a steady influx of workers. Currently there are between 35-40 workers from around the world serving in six different provinces: Tak, Sukhothai, Kamphaengphet, Phitsanulok, Chiangmai, as well as the capital Bangkok.
Initially, the only Christians in the northern provinces were some believers from Burma who had settled near the border. The early years saw little response, but now we are witnessing a new openness to the Gospel, with people turning to Jesus regularly."
WEC Thailand has used various methods of outreach over the years. In the early years, leprosy outreach was established. Literature and films have played an important role, as have radio and cassette work. Today, evangelism and church planting are done in partnership with the emerging Thai and Karen leadership.
In 1999, WEC helped co-found the Grace International School in Chiangmai, and has since committed to the ministry of educating missionary children.
In 2014 WEC Thailand made the decision to embrace Missional Business as a strategy to compliment our church planting strategies. Together they will work towards transforming communities.
