Grace Gospel Association of Africa

Location & Work

Equipping Churches. Empowering Communities.

The Grace Gospel Association of Africa (GGAA) is a growing network of churches across Kenya committed to equipping pastors, strengthening local churches, and advancing the Gospel. Led by Bishop Zack Nandi, GGAA brings together churches around a shared commitment to biblical teaching, discipleship, leadership development, and compassionate community outreach.

Serving churches across eight counties in Kenya, GGAA helps pastors and congregations become healthy, reproducing communities of faith that are transforming lives through both the message and the practical love of Christ.

What They Do

Leadership Development

GGAA equips pastors and church leaders through biblical training, theological education, leadership conferences, and mentorship. These programs help leaders build healthy churches that are firmly rooted in Scripture and equipped to disciple others.

Church Strengthening

By providing ministry resources, coaching, and ongoing support, GGAA helps local churches grow in spiritual health while fostering unity, accountability, and collaboration among church leaders.

Revival and Discipleship

Monthly revival meetings and regional gatherings encourage pastors and congregations through worship, prayer, biblical teaching, and fellowship. These events strengthen believers and renew churches in their mission to reach their communities.

Church Planting

GGAA is committed to expanding God’s Kingdom by helping establish new churches in underserved communities while mentoring leaders who can multiply disciples and raise future generations of church planters.

Community Empowerment

GGAA believes the Gospel is demonstrated through practical acts of compassion. Through member churches such as Heart of Worship Ministries, the network supports vocational training for vulnerable women, entrepreneurship programs, and initiatives that strengthen families and create sustainable livelihoods.

Future community initiatives include providing sanitary products for vulnerable schoolgirls and expanding educational support for children who would otherwise be unable to attend school.

Who Are We Partnering With?

ImpactHope is partnering with Bishop Zack Nandi and the Grace Gospel Association of Africa (GGAA), a growing network of churches, pastors, and ministry leaders serving communities across six counties in Kenya. As the Founder and Presiding Bishop of Heart of Worship Ministries, Bishop Zack leads GGAA’s mission to strengthen local churches, equip Christian leaders, and advance the Gospel through discipleship, church planting, leadership development, and community outreach.

Through biblical training, mentorship, revival gatherings, and strategic partnerships, GGAA helps churches become healthy, reproducing communities of faith that are transforming lives and sharing the hope of Christ across Kenya. Their vision is to see a united and mission-focused Church that is making disciples, planting churches, and bringing lasting spiritual and community transformation.

Tatiana's Story

From a very young age, Tatiana had a heart for serving children. After a short trip to help at an orphanage in Haiti in 2014, she was ready to go all in to serve the less fortunate children of the world. Tatiana was the driving force behind the family moving to Peru, and she loved the children of Peru.

In the summer of 2018, Tatiana Blackburn died tragically in a car accident. To honour her memory, the Blackburns started a fund called Tat’s Kids Peru. This fund was designated for the children at Tat’s Place to support the ongoing operation of the home.
