Karl teaches missions and church history at Bangkok Bible Seminary, assists with translation and editing at Kanok Bannasan (OMF Publishers Thailand),
one of the few publishers of Thai Christian books, and preaches at local churches. Living right next
to the seminary campus in downtown Bangkok, both Karl and Sun have
opportunities to invest in the lives of students, the next generation of
Thai church leaders. They are also involved in ministry with local
Thai churches, laboring to see healthy models of biblical teaching and
Christian living take root in the lives of Thai Christians.
