Our History
Entrust, equipping and training
Entrust began in 1979 to help Christians isolated from other believers by the so-called Iron Curtain. Several ministries working secretly and individually in Soviet-controlled places, focusing primarily on discipleship and evangelism, recognized the need for training for pastors and church leaders. They joined forces for greater efficiency and maximum kingdom impact.
With the fall of communism in 1989, Entrust was in place to help national believers and new mission groups navigate new freedoms in Eastern Europe. Soon, God opened doors, allowing Entrust to share its non-formal, biblical ministry training in many new countries and continents.
One Challenge, equipping and mobilizing
One Challenge was born in 1952 when missionary Dick Hillis followed God’s call to help the global church grow stronger and reach farther by equipping and mobilizing people around the world. What started with a few people serving pastors in Asia has become a global movement. OC staff and partners now work alongside national churches and leaders in more than 50 countries, helping them develop leaders, plant churches, and share the gospel in their own communities.
Entrust and One Challenge, joining together
In January 2025, the Boards of Entrust and One Challenge, recognizing the common vision, mission and values shared by both organizations, voted unanimously to merge.
In October 2025, OC and Entrust became one.
Our shared legacies of equipping leaders, leadership development, mobilizing, disciple-making and cross-cultural ministry will continue on and grow stronger as we serve together.
