Behind every ministry are real people — families who have chosen to give their lives to seeing the Gospel reach those who have never heard it. Meet some of the workers One Challenge supports, and learn about the global family they are part of.
The People of One Challenge
Our Workers
Our workers serve in many different countries and contexts – some in places where the Gospel has been present for centuries, others in places where it is still fragile and new.
Each brings their own story, gifts and calling; all share the same commission.
We would love to connect you with them. Every family benefits from more people praying, writing and standing with them. To start receiving prayer updates and newsletters directly from our workers, write to us at info@onechallenge.org.uk
For those working in sensitive regions, we will ask you to provide a pastor or Christian minister as a reference before connecting you directly. Getting involved in this way is a challenging and exciting way to discover what God is doing in the world today.
Don and Nancy joined the OC International UK team in April 2010, having already served in Austria for over 20 years. After more than a decade in business, they entered full-time ministry in 1986 and moved the following year — with their three children, Alyssa, Amy and Matthew — to the south-eastern suburbs of Vienna.
In the early years of their ministry, they focused on discipleship, evangelism and church planting training across the former Eastern Bloc, shortly after the fall of communism. In 1991, the Lord directed them toward working within church planting teams across a wide denominational spectrum. Today, they continue mentoring Austrian leaders in all aspects of church ministry — including equipping the church in Austria to look outward and engage in mission beyond her own borders.
With a passion for the unity of the body of Christ, Don and Nancy remain involved in one of Europe's most developed works of unity — the Way of Reconciliation Round Table.
Their children have grown and are living fruitful lives in God's Kingdom. In 2007, Nancy's mother Irene came to live with them in Austria, where Don and Nancy provide her care.Austria is home to approximately 8.3 million people. It is one of the most secular, predominantly Roman Catholic countries in the world, and the evangelical witness remains less than 1% of the population.
Richard and Katherine come from two countries in North Africa and the Middle East. For security reasons, their full names cannot be made public. Richard was born into a Christian family; Katherine came to faith in Christ while living in London. They have one son.
Their ministry is focused on recent disciples of Jesus Christ in the Arabic-speaking world. Through visits arranged by churches and Bible schools, they help new believers discover what the Bible teaches — and what it requires. Cultural attitudes are gently but firmly brought under the authority of Scripture; and radical transformation follows, especially in the lives of those God is raising up as leaders in emerging communities.
In addition to their international work, Richard and Katherine are currently helping an Arabic-speaking church in England, while their son completes a pre-university course nearby.
Pray for our workers

One Challenge
The OC Global Alliance
One Challenge is a founding member of the OC Global Alliance — a family of thirteen centres around the world, each sending out workers internationally: across a cultural divide, or into a context requiring a new language.
A global family with a shared mission
The Alliance brings together organisations from diverse church traditions and national backgrounds, united by a common commitment to the Great Commission. Member centres meet every two years to discuss strategy, share stories, and decide how best to work together as new opportunities arise — many of them with the potential for significant impact on whole nations.
Over time, the Alliance has developed clear guidelines for multi-national teams: how to navigate diverse church cultures, how to collaborate well, and how to make the most of varied gifts and backgrounds within a single ministry. The result is a richer, more resilient form of mission than any one centre could pursue alone.
