Kyle & Cindi Tumberg

Kyle, Cindi & Ali Tumberg have been Career Missionaries since 2012, serving the Central Thai Buddhists of Thailand.

We have been serving as missionaries in Thailand since November of 2012, but our journey to missions started long before then. Several years prior, I was made aware of the incredible needs of the unreached world, and for the first time in my life I had an inkling that God might be calling me to go. About a year later I began dating Cindi, my future wife. We were actively involved in a church-planting project in Arkadelphia, AR and eventually began contemplating long-term mission service. In 2009, about four months after we married, we decided to apply with Adventist Frontier Missions. For the next couple of years we wrestled with whether or not God was truly calling us overseas. Finally, in the spring of 2011 after a week of fasting and prayer, we surrendered fully to the Lord and told Him that we were willing to go wherever He might send us, and that we would go as far forward as He led.

God led us to Khon Kaen Thailand where we have been living since 2014. We are working with a committed team of people to establish a strong church in this growing city with no Adventist presence. Although we are not music teachers, we work with Peace Music Academy to build relationships and to offer services to the public. We also work closely with a local Adventist pastor to plan evangelistic events and outreach endeavors. Our goal is to establish a strong national church body with the burden to conduct effective city ministry based on Biblical and Spirit-of-Prophecy principles.

A Spiritual Perspective

As I reflect on my experience with Bon and Cherry over the past year and a half I can see that God had a plan and a purpose in bringing them to Khon Kaen to work with us and also in having them leave when they did.

I can’t help but be amazed at what God has done in Joon’s life. I know that God has a special plan for Joon and that he is not done growing yet.

Andru told me that God was putting a burden on his heart to hold a youth camp in Khon Kaen so that he could share with his friends what he had been learning. He asked if I would help him plan it, and I was happy to agree.

Meet Alison Tumberg

I miss seeing all my friends at church and shopping with my mommy. But one thing I have really enjoyed is going to the train station and passing out food to all the people there who have lost their jobs.

Other-Worldly Peace

We will truly be “a spectacle unto the world, and to angels, and to men” (1 Cor. 4:9). It is my prayer that we all can experience God’s true other-worldly peace no matter what situation we find ourselves in so that others can be drawn to Him.
