Seventy Years Strong: The Past, Present, and Promise of Japan Open Bible
On October 31 – November 5, 2025, Japan Open Bible Churches celebrated their seventieth anniversary. Global Missions Director Vince and Lois McCarty, Open Bible President Michael and Julie Nortune and I were honored to join them for this celebratory occasion.
My own connection with Japan goes back to my twenty-third birthday when I boarded a plane to Kobe with two suitcases, only five words in my Japanese vocabulary, and a heart full of missionary zeal. During my six years there, the Japanese church shaped me deeply as both a missionary and a person. When I left Japan thirty-six years ago, I left a piece of my heart. Joining them again to celebrate seventy years brought me real joy!

Japan Open Bible has become a true partner in ministry with Open Bible Churches globally, a partnership especially visible across Asia. The anniversary celebration honored the legacy of Japan Open Bible missionaries and the heritage of churches they planted while also affirming the importance of today’s smaller, community-based congregations. We visited, preached in, and celebrated with churches and pastors in both eastern and western Japan.
Japan’s geographical isolation and a 250-year ban on Christian missions in the sixteenth and seventeenth centuries gave Japan a reputation as “the missionaries’ graveyard.” Yet, after World War II some US veterans, having seen the spiritual vacuum in Japan, returned as carriers of the hope of the Gospel. The Jake Collins, Eddie Carnes, and Phil Rounds families were among the first in the 1950s era to be sent by Open Bible Churches.
From a handful of missionaries and new believers in the early years to a network of Open Bible Churches across Japan today, God’s presence has been a steady flame of hope in the darkness.
From a handful of missionaries and new believers in the early years to a network of Open Bible Churches across Japan today, God’s presence has been a steady flame of hope in the darkness. Even though fewer than one percent of Japanese identify as Christian, today across Japan we see our churches, large and small, alive with joy and power of the Holy Spirit.
One of the early converts, now ninety-year-old Yaeko Yoshinaga, is likely the oldest surviving member of those first Japan Open Bible congregations. As an eighteen-year-old, she lived with the Rounds family helping in the home. She loved their children and learned to love potatoes (more than rice) as they did, but even more, came to faith in Jesus Christ.
Yaeko says, “I would not have believed in Jesus if I had not met Mr. Rounds, the missionary.“ She and her husband later pastored for 45 years, and today her son and wife pastor the flourishing church. Decades later, the flame of God’s love still burns brightly in Yaeko sensei. Her love, joy, humility, and faith impact every generation in the church. She remains a powerful reminder of how one relationship can change the direction of an entire life.
Pastor Yoshio Ishikawa told me the story of how he came to Jesus as a young boy. In the late 1960s, ten-year-old Yoshio’s family lived near an Open Bible Church in the Sumida neighborhood of Tokyo. He recalls, “When I was ten, I saw a TV drama about an incurable disease. It scared me, and without really knowing why, I walked into the church in my neighborhood that I had passed by many times. That church was Sumida Open Bible – the church I now pastor.”
Today, Pastor Ishikawa uses his talent as a skilled musician to reach people in new, non-traditional ways. He teaches a group ukulele class as a bridge to the gospel. Students learn to play the ukulele, then hear a teaching from the Bible and join in prayer. Other approaches, like book clubs, English lessons, and choirs, give churches relational ways to connect and open doors for evangelism.
In fact, many “unconventional” forms of evangelism are used to touch lives in churches in Japan. Often, churches and Christians invest years building trust and relationships before someone decides to follow Jesus. In my own experience, I saw that converts under my ministry were often a result of groundwork laid by others before me.
Looking ahead, Japan Open Bible embraces a bold vision: to plant ten new churches throughout the country in the next decade. I, for one, believe it can happen! God has not abandoned Japan. The hope of the Gospel that the missionaries brought with them back in the 1950s continues to burn brightly in our brothers and sisters of Japan Open Bible. May God fan that flame as they carry His hope across the country in ways we have not yet imagined!
As I leave Japan once again, I reflect and am grateful to have shared in the celebrations of what God has done, excitedly anticipating what He will do next!

“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.
School of Global Leadership
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.
Looking to the Future
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.
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.
About the Authors

After serving as teachers at a public high school in Nebraska and as associate pastors in their local church, God expanded their calling into full-time missions. Throughout their marriage, God has woven a passion for the nations into their hearts. They currently serve within the School of Global Leadership (SGL) in Trinidad and Tobago. Their ministry includes hosting missions teams, leading missions training, and partnering with local churches. They are grateful for all God has done and look forward to all He will continue to do in and through their lives.
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!

Have you ever wondered, What in the world are our Open Bible missionaries doing now? We wish we could visit every church or sit down over coffee and share what God is doing where we serve—but that isn’t always possible.
So this month, we’ve gathered brief notes from missionaries around the world. As you’ve read these updates from around the world, we invite you to pray for our missionaries—their families, their ministries, and the communities they serve. Please also share these stories with your church so others can join in prayer.
