  • Kowit Kamkaew, and Orapin Nathewa Samuel Kamkaew.
  • Location: Pastor at Mahasarakham
  • Ministering in Thailand: With OMF since 2023
  • My wife and I came to know the Lord in August 2012 while we were in South Korea. God called us through the Bible verse Isaiah 6:8, which says, “Whom shall I send? And who will go for us?” And we responded, “Here I am. Send me.” In 2013, God led us to attend Bible study in Korea for four years, during which we were actively involved in evangelism and discipling Thai people living in South Korea. I took care of a group of young people, while my wife ministered to the LGBTQ community. In 2018, God brought us back to Thailand to further our biblical studies at Bangkok Bible Seminary for three years. My vision is to pioneer churches and make disciples in the Northeast, the South, or in places where there are no churches. God has led my family to the Northeast to work with missionaries so that together we can establish a new church. I am now the pastor of the Bible Christian Church of Mahasarakham, and my wife and I are dedicated to community ministry.
