Faithful Witness Among Muslim Communities

Across the world, believers serving among the Muslim communities navigate a rapidly shifting global landscape. According to demographic projections highlighted in Lausanne’s report on Islam¹ – the fastest growing religion in the world – the global Muslim population is expected to comprise 26.4 per cent of the world’s population by 2030, with growth accelerating fastest across sub-Saharan Africa. This rapid expansion brings severe pressure points, ranging from strict local enforcement of Sharia Law to heightened religious nationalism, which translates into intense social friction and familial rejection for Christian minorities.

Furthermore, Lausanne’s data on ‘what is the source of hope’² for global missions underscores a stark demographic reality: historic surges in conflict, economic hardship, and urbanisation have physically displaced millions of people. These migration patterns have given rise to massive diasporic communities, shifting the mission field directly into previously homogenous nations. Overcoming fear and maintaining an authentic, Christ-like presence among these vulnerable populations is vital.

Shared during the Fourth Lausanne Congress, the following stories highlight a common thread: faithful discipleship, relational ministry, and long-term perseverance continue to bear fruit, even in places marked by opposition, displacement, or spiritual resistance.

Courageous Discipleship Amidts Persecution

Lucy Chengo | Kenya

Serving among Muslim communities in Kenya, missionary Lucy Chengo has walked closely with new believers who often face rejection from their families and communities after choosing to follow Christ. Yet amidst persecution, she has seen disciples become bold witnesses to others.

One testimony particularly encouraged her. A young believer she discipled was rejected and cast out because of his faith, yet he remained steadfast while continuing his education and spiritual growth. Today, he is not only sharing the gospel among his own people but also reaching Somali communities around him.

Reflecting on this transformation, Lucy shared that hearing similar testimonies from women during the congress strengthened her deeply. She said it encouraged her to see women growing as leaders in God’s mission, taking on vital roles in high-pressure ministry contexts.

Planting Churches Where Christians Are a Minority

Monday Amoak | Ghana

In northern Ghana, Monday Amoak serves in communities where Christians are often minorities and where establishing churches can be difficult. One of the greatest challenges his ministry faces is securing permanent places for believers to gather.

‘Because it’s a Muslim area . . . we’re finding it hard to get a permanent place to meet,’ he explained.

Despite these obstacles, the work continues to grow. Alongside church planting, Monday is involved in leadership development through a pastoral training initiative. The programme equips pastors who have never had the opportunity to attend seminary or Bible college, bringing theological education directly to where they live and minister.

So far, more than 40 pastors have completed training in several locations, and the ministry is expanding into new regions, including areas near the border of Burkina Faso.

Sustainable gospel growth often depends not only on evangelism but also on equipping local leaders for long-term ministry.

Monday’s testimony highlights an important reality in global mission: sustainable gospel growth often depends not only on evangelism but also on equipping local leaders for long-term ministry. In regions where resources are limited and opposition is common, leadership development becomes essential for strengthening the church.

His request to the global church is simple — pray for endurance, wisdom, and lasting impact as churches are planted and leaders are trained across West Africa.

Faithful Presence Over Decades of Ministry 

Walter Gonçalves | Bosnia and Herzegovina

For more than 25 years, Brazilian missionary Walter Gonçalves has served in Bosnia and Herzegovina, ministering in a majority-Muslim context through church planting, discipleship, and compassionate outreach.

Over the years, the ministry has grown beyond establishing churches. Walter and his team have also helped train and send missionaries, watching young believers step into ministry themselves. Though releasing them has sometimes been painful, he sees it as part of God’s work of multiplication.

Walter’s journey has also included personal challenges. Even after becoming wheelchair-bound, he continued serving faithfully. As he simply stated, his condition didn’t stop him doing ministry and church planting.

Recently married at the age of 60, Walter and his wife have also opened their home to vulnerable children. One young boy came from a deeply broken family situation, while another was placed with them through a government programme. Together, they are raising the children while continuing their ministry among local communities.

 Gospel witness is often sustained not through large platforms or rapid success, but through long-term faithfulness, hospitality, and presence.

His testimony illustrates how gospel witness is often sustained not through large platforms or rapid success, but through long-term faithfulness, hospitality, and presence. In contexts where visible fruit may take years to emerge, a consistent and compassionate witness can quietly transform lives.

Reaching Muslim Migrants Through Language Classes

Heidi Planchart | Spain

Originally from Venezuela, Heidi Planchart now serves in Spain among Muslim migrants from across the Middle East and Africa. Through Spanish language classes, she has found a simple yet powerful way to build relationships and share the gospel.

Working with people from more than 14 nationalities — including Morocco, Syria, Mali, and Sudan — Heidi sees increasing openness among migrants searching for hope and belonging in a new country.

‘We are working through Spanish classes. It is the platform we are using to reach Muslim migrants in Spain,’ she explained.

What begins as practical assistance often develops into deeper spiritual conversations. Heidi and her team have started offering New Testament and reading Scripture with some of the migrants they serve.

She believes her Latin American background has unexpectedly helped create connection and trust. The warmth, hospitality, and relational culture familiar to many Latin Americans often resonates deeply with Muslim communities.

Her testimony reminds the global church that everyday skills such as teaching language, offering hospitality, or serving practical needs can become meaningful bridges for gospel witness in diaspora contexts.

God Continues to Move

Though these stories come from different regions and ministries, they reveal common themes: perseverance amid hardship, the importance of discipleship, and the power of relational ministry. They also remind the global church that God is at work among Muslim communities in ways both visible and unseen.

Some believers are planting churches in difficult regions. Others are discipling new followers of Jesus who risk rejection for their faith. Some are opening homes, teaching classes, or training leaders. Together, these acts of faithful obedience are contributing to the spread of the gospel across cultures and nations.

These testimonies invite believers everywhere not only to celebrate what God is doing but also to pray, collaborate, and participate in his mission among the nations.
