Those were some of the most exciting words we ever heard when we were younger. As smoke billowed and restraints were released, thousands of tons of steel lifted into the air. There was a course, a destination, a goal, and even a plan, however, everybody knew anything could happen. Welcome to CSOM (Calvary School of Missions). By the time you read this, we are through the final countdown and have arrived at our destination. Bags were packed, vehicles serviced, a course prepared, a destination, a goal, and even a plan, however, everybody knows anything could happen. But unlike a rocket to outer space, our sovereign, all-powerful, all-knowing Father is in complete control. We are completely dependent on Him!!  Also, we are so grateful for your prayers, encouragement, and partnership in the Great Commission!! Did you know that the great commission isn’t a calling? It’s a COMMAND!

Meet the students & staff:

Jesus said, “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age.” – Matt 28:19-20 

We are super blessed that we get to be a part of His Great Commission!! We had it on our hearts to share with you a short answer to these two questions: “what is the unreached?” & “what is the 10/40 window?” We have been asked these questions a lot and want everyone to know!

CSOM students will spend the next six weeks learning the answers to these questions and understanding the need so please understand this is a condensed explanation that we would welcome you to contact us about so we could explain more in person. 

What is the unreached ?  

Definition: a population with less than 5% claiming to be Christian and of that, less than 2% evangelical.

The term “unreached” also refers to a people group among which there is no indigenous community of believing Christians with adequate numbers and resources to evangelize this people group.

What is the 10/40 Window?   

I, Jenn, hear a lot of people ask me, “what is the 10/40 window?”  It’s a common question, I myself didn’t know what it was until 10 years ago when I began studying the Great Commission and learned what the purpose of the church is. The purpose of the Church’s existence on the Earth is for the evangelization and discipleship of all people.

The 10/40 window is a rectangular area of North Africa, the Middle East, and Asia between 10 degrees north and 40 degrees north latitude. It is often called, “The Resistant Belt,” and includes the majority of the world’s Muslims, Hindus, and Buddhists. There is an estimated 5.37 billion individuals that reside in approximately 8,762 distinct people groups. 

The 10/40 window is home to the majority of the world’s un-evangelized countries. The “un-evangelized” are people who have a minimal knowledge of the gospel, and have no valid opportunity to respond to it. While it constitutes only one-third of earth’s total land area, nearly two-thirds of the world’s people reside there. That is a massive amount of people who if they were to die today, would stand before God in judgment for their sins, never having heard the name of Christ, never having had the chance to put their faith in Him for forgiveness of their sins.

We have the privilege to lead the Calvary School of Missions into an indigenous unreached tribe in the mountains of Mexico in August. This will be the 2nd year we are able to take the gospel and the love of Jesus to the tribe.

We look forward to seeing how the Lord will use us this year to these beautiful people!!

Here are a couple of videos you could watch to further understand our passion for the unreached: “Tears of the Saints” on YouTube, “The Great Imbalance,” and “Risk it all for Christian Mission.”

Praise reports:
God is moving in Andy’s life. He has just completed 20 days in an inpatient hospital. Jenn was able to spend time with Andy before leaving for 6 weeks. Tim’s back is improving and we as a couple are implementing personal disciplines that will help enable us to serve the Lord in this capacity. Jenn is recovering well from surgery.

Prayer requests:
Please pray for the 2024 Calvary School of Missions.  Wisdom and sensitivity to the leading of the Spirit as we plan out the rest of this year’s missionary care calendar.   Please pray that as a couple serving together in the office and on the field, that we continue to be steadfast in the Lord.   Please continue to pray for Tim. Although he is improving, he still continues to have back pain. Please pray for continued healing for Jenn. Pray for Andy’s salvation and his willingness to surrender his ways.
