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.

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.

Build Hope for Africa: A Story from Nigeria
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.

Global Harvest Offering 2026: Building Hope in Africa
Ask Open Bible pastors in Africa what the biggest problem in their church is and most reply with one word: REVIVAL! Just as Saul once ravaged the early church in Acts 8, our African brothers today face similar conditions: harassment, arrest, and even death for following Christ. But in the face of persecution, our churches are experiencing rapid growth in thirteen African nations. They’re calling for our help, not to alleviate the suffering, but to build new church facilities to serve their expanding congregations and communities.
The Global Harvest Offering of 2026 is “Building Hope in Africa,” and it is our opportunity to participate in this revival. In this initiative, we will partner with our missionaries and national directors to fund thirteen new church building projects across the continent. God is using faithful missionaries and nationals to plant churches, raise leaders, and reach communities with the hope only found in Jesus!

… in the face of persecution, our churches are experiencing rapid growth in thirteen African nations.
Our missionary partners are many: the Godwins, the Kopps, the Parkers, Okon Obot, Peter Mahoye, the Moores, the Welches, and our brothers and sisters throughout the Antioch Network.
Thirteen churches.
Thirteen countries.
One goal:
to raise the $200,000 needed to
cover the costs for all thirteen projects.
With over 230 Open Bible churches in the United States, we can meet the financial goal of the Global Harvest Offering if each church gives $875. Alternatively, just 2,000 people giving $100 this year would meet the goal. Your support in this effort helps build more than walls; it builds hope, community and the Kingdom of God.
