Dear Co-laborer in Christ,
The "heat-map" on the right shows the sub-districts in Thailand where churches are located. A yellow colored sub-district means there is a church located in one village. Orange and red colored areas indicate more than one church is located in that sub-district.
From the picture, you can see that where the gospel has been planted, it spreads. In fact, 87% of Thai Christians live in a sub-district that has more than one church.
However, 76% of all sub districts have no church. (The dark blue areas on the map) Those people have very limited opportunity to come to know Christ.
