We’re Pete and Sumari Witt, missionaries serving in South Africa since 2018. Based in Johannesburg, we invest in spiritual formation, emerging Christian leaders, local churches, and gospel outreach—helping believers know Jesus deeply, live according to His Word, follow the leading of His Spirit, and make disciples wherever He sends them.

Forming Disciples Who Know Jesus and Make Him Known
We long to see believers deeply rooted in Jesus—formed by Scripture, led by the Holy Spirit, growing in Christlike character, and equipped to strengthen local churches and make disciples wherever God sends them.
What Our Ministry Looks Like Today
Discipleship and Spiritual Formation
Through long-term, relational discipleship—including the ROOTED Discipleship Journey—we help believers grow in intimacy with Jesus, become grounded in Scripture, hear and obey His voice, and develop lives of prayer, worship, character, and service.
Equipping Emerging Leaders
We teach, mentor, and walk alongside emerging Christian leaders, helping them grow in biblical understanding, spiritual maturity, leadership, and practical ministry experience.
Strengthening Local Churches
Our family serves within City on a Hill Johannesburg, where Pete is an elder. We also teach, preach, encourage leaders, support church plants, and partner with churches in South Africa and internationally.
Gospel and Outreach
We share the gospel and serve through local churches, schools, ministry among children and young people, community outreach, and opportunities God opens across South Africa and beyond.
