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.

I am more and more convinced of the power of prayer, and I am grateful for the many people who have prayed for us and for our work. May we continue to pray earnestly and expectantly!

We continued to pray for Kat, but I didn’t have much hope that she would come back to God. Thankfully, He didn’t give up on her.

Where Were You?

I urge you to plead with God to make you an agent of change wherever you are. May the Lord stir our souls and give us the courage to take an active role in stemming the tide of evil that is engulfing our world.

Please pray for Yod and his parents, and pray that our church and school will truly reflect God’s character so that many others will be drawn to the Savior.

Untapped Resource

I give God the glory for how He is tapping into untapped resources and calling our Filipino members to serve as missionaries for Him.
