Our Journey from Pastor to Missionary and Back

Published

After thirty years of pastoring in the U.S., God called us to be missionaries to Hungary and Romania, where we were introduced to new cultures that changed the ways we saw ministry. The first thing we noticed was the way the Open Bible churches, both in Hungary and Romania, went out of their way to help us get settled into our new homes. They helped us find an apartment and went with us to get utilities hooked up and all the other legal things that were required to live in their country. We have often thought since then that churches in the United States may be missing out on a ministry opportunity. Could we do a better job of helping new residents to our communities, especially those who are from a different culture and do not speak the language well? 

Another thing that impacted us was listening to the stories of the older saints. Both Hungary and Romania are former communist countries. It was sobering to hear the testimonies of those who experienced persecution, imprisonment, and loss of jobs and property because of their faith. It was fascinating to hear these old saints pray. They knew how to enter the throne room of heaven when they prayed. 

One cultural difference we noticed was their attitude towards time. Americans tend to be very time conscious and expect things to begin and end on time. Our language classes at the University in Debrecen were filled with students from many countries. It became a joke that the American, German, and Japanese students would arrive to class early while the other European students would usually come late. Although they followed schedules and made appointments, relationships were more important than schedules. As a result of that cultural difference, we learned to be flexible and “go with the flow.” For example, one time we were planning on getting some work done at home when we received a call from a member of the church. They stated that a family was planning a picnic and wanted to meet us, and they wondered if we would be interested in joining them. We said we would like that and asked when the picnic was, and they said, “Now!” So we changed our plans and went to the picnic. 

Sándor and Margó Pántye

Of course, the main challenge was learning a new language and adapting to new foods and different ways of doing things. It did not take us long to realize that the American way is not always the best way and that just because something is different does not mean it is wrong; it is just different. We grew to enjoy the different food and culture of our new home. 

As far as the impact our ministry had upon the people of the countries in which we ministered, we often heard testimonies of how thankful they were that we would leave our home and family to come and minister to them. They especially appreciated that we would make the effort to learn their language and live among them, that their home country became our home also.  

What thrilled us the most was seeing the growth of those who studied INSTE. It was exciting to see their hunger to learn the Word of God and to watch them become involved in the work of the church, even taking on leadership roles. One example is Sándor and Margó Pántye. They have been faithful in the Open Bible Church in Debrecen, Hungary, for years. Sándor played the guitar on the worship team, and Margó served in small ways where needed. Since graduating Level One INSTE, however, they have both become more involved in ministering in the Open Bible churches in the villages. Sándor leads worship while Margó has stepped up into a role of teacher.  

This only makes us realize, though, that we are still missionaries regardless of which country we are in. 

During our thirteen years as missionaries, we have often thought of Jesus’ words: “And everyone who has left houses or brothers or sisters or father or mother or children or lands, for my name’s sake, will receive a hundredfold and will inherit eternal life” (Matthew 19:29, ESV). This is definitely true for us because we have developed many, many close friendships that will last forever. 

Now that we have moved back to the U.S., how has the transition been for us and how has our ministry been affected by our experiences overseas? There has been a little “culture shock” upon returning to the U.S., especially in the grocery stores when we see the aisles filled with so many options. In fact, sometimes the number of choices we have can be overwhelming. Also, America is not the same country it was when we left thirteen years ago. Even though we have been following the news from overseas, it is still disheartening to see what has happened to our country. This only makes us realize, though, that we are still missionaries regardless of which country we are in.  

As we begin our new ministry in the church here in Hardin, Montana, one of the things that we are bringing back with us is a change in our focus. Our emphasis will not be on developing programs to enlarge the size of the congregation but will instead be on building up people. A major emphasis will be on prayer, the baptism in the Holy Spirit, and discipling people so they will be spiritually healthy enough to disciple others. We believe that as we center our attention on these areas, God will add to the church daily those who are being saved (Acts 2:47).

From Generation to Generation

“We will not hide them from their children, telling to the generation
to come the praises of the Lord, and His strength and His wonderful works that He has done”
(Psalms 78:4 NKJV). 

On March 1, 1967, Melvyn and Barbara Kelderman moved to Trinidad and Tobago. That step of obedience began a family legacy that decades later led us—their son and daughter-in-law—to return as full-time missionaries serving with the School of Global Leadership (SGL). Looking back, we see God’s faithfulness from one generation to the next.  

Before being appointed as missionaries in 2024, we both taught secondary school while serving at Open Bible Church in Omaha, Nebraska. During those years, God gave us countless opportunities to grow in ministry and deepen our calling. Having served in cross-cultural ministry in several countries, we were grateful when He opened the door to join Global Missions full time. Today we serve with the School of Global Leadership, helping believers discover their role in God’s global mission and equipping those who are moving from called to sent. 

Outreach with Open Bible Standard Churches of Trinidad and Tobago (June 2026)

Since its beginning in 2010, SGL has helped revitalize the vision for missions within the Open Bible Standard Churches of Trinidad and Tobago. Their work in Trinidad and beyond has helped SGL to become a partner with the Global Missions department in helping connect, expand, and reach into other countries around the world with the Gospel. 

One of SGL’s greatest joys is hosting teams from Open Bible Churches in the United States. These short-term ministry experiences allow participants to encounter Trinidad’s diverse religious landscape, including Muslim, Hindu, and African-derived faith communities, while discovering how God may be calling them to serve. SGL also equips future missionaries through online courses and hands-on training. Whether you’re exploring God’s call, preparing for long-term service, or simply wanting to learn more about His work among the nations, we’d love to help you take your next step. 

While Trinidad remains our training base, we believe God is expanding this vision. Our hope is to establish SGL training hubs in Europe, Asia, Latin America, and Africa so that future leaders can be equipped within their own languages and cultures. As we continue partnering with Global Missions, we believe God will open doors to train and equip missionaries from everywhere to everywhere. 

Leading Worship with Faith Fellowship Mission Team (June 2026)

We are deeply grateful for the churches and individuals who pray for us and faithfully support this ministry (Philippians 1: 3). Together we are helping prepare the next generation of workers who will carry the gospel to the nations. Just as others invested in us, we now have the privilege of investing in those God is calling today – and we believe He will continue telling His story from generation to generation.

Build Hope for Africa: A Story from Nigeria 

Published

on

In parts of Nigeria today, land is no longer just a livelihood – it’s a battleground. In search of increasingly scarce water and grazing land, semi-nomadic Muslim herdsmen are moving their flocks south into areas already inhabited by Christian farmers. This encroachment has intensified conflict, resulting in thousands of deaths, the displacement of millions, increased kidnappings, and deepening ethnic tensions. This is the environment in which Open Bible’s ministry continues day after day. 

Despite these challenges, the Gospel is advancing. 

Okon Obot, Open Bible’s Superintendent in Nigeria, shared the following story with me: 

Recently we held an evangelistic crusade in one of the affected regions. Despite security concerns, people came looking for hope and peace. Evangelistic crusades remain a powerful and effective way to share the Gospel in village communities where fear and uncertainty are a part of daily life. 

The theme of the crusade was “Arise and Shine,” and over 300 people gathered. By the end, sixteen people had given their lives to Jesus and fifteen were immediately baptized and welcomed into the church, each a testimony to God’s faithfulness. 

A high point of the crusade was the reconciliation of a family of brothers divided for five years. Under the conviction of the Holy Spirit as the Word of God was shared, they chose forgiveness and were restored to one another. They returned to their homes with joy and peace. 

In response to God’s work in their lives, the brothers donated a large piece of property in their village, Mbabuu, for the construction of a church building. 

This is where the 2026 Global Harvest Offering, “Build Hope for Africa,” comes in. When we reach our goal of $200,000, Nigeria will be one of the recipients. Open Bible will partner directly with Pastor Okon to build a new church building in a place like the village Mbabuu. 

This is more than a construction project – it is the next step of what God is doing. Despite hardship, churches in Nigeria are growing and new buildings are needed to serve expanding congregations and reach their communities. 

Your gift to “Build Hope for Africa” can help provide a visible witness of Jesus in a region marked by instability and equip local leaders like pastor Okon to continue evangelizing where the need is great. 

In a place where land is fought over, God continues to build His Church!
