In July 2001, Bill Johnson traveled to Kenya on what became the first of ten mission trips, where he met Rev. Simon Mwaura, who was planting his first church in Wanjohi. Through Faith Ventures Foundation, Simon received leadership training in the United States and, in 2002, sensed God's call to take the Gospel to Kenya's 22 unreached tribes. He began ministering to the Samburu people in 2003, and in 2006 Faith Ventures Foundation provided a four-wheel-drive Land Rover to support the demanding travel required to reach these remote communities.

After joining St. Michael's Anglican Church in Charleston, South Carolina, the Johnsons encouraged the church to deepen its commitment to the Great Commission. This led to a Global Outreach seminar in 2008, where Simon and his wife, Lucy, confirmed God's call to establish God's Grace for All Nations (GGFAN), a ministry dedicated to bringing the Gospel to all 122 tribes in Kenya. Supported by Faith Ventures Foundation and several ministry partners, GGFAN quickly expanded its reach.

In 2011, after meeting with pastors from across Samburu County, the Nkalup Vision was born—a shared commitment to plant 1,000 churches and raise 50,000 followers of Jesus throughout the county. A subsequent census revealed only 158 churches serving approximately 6,250 Protestant Christians, highlighting the need for widespread church planting. Rather than relying on outside missionaries, the vision focused on equipping local believers through leadership training, church planting curriculum, and partnerships across denominations.

Over the following years, the movement gained momentum. The Samburu County Nkalup Vision (SCNV) became an officially registered Kenyan charity, enabling financial support for new preaching point leaders and regional coordinators. Additional partnerships funded transportation, clean water systems, church planting initiatives, leadership development, and governance improvements. As more denominations embraced the vision, SCNV expanded its leadership and strengthened accountability while continuing to multiply new churches throughout Samburu County.

By the end of 2017, SCNV had achieved 55% of its goal of planting 1,000 churches and had trained more than 600 pastors, becoming the largest church planting movement in Samburu County. While celebrating this remarkable progress, the ministry recognized that much work remained and continued pursuing its vision of ensuring every community in Samburu County would have access to the Gospel.
