Randy Shares The Story

A Multiplying Movement is Growing

When Randy and Carol moved to Atlanta to plant Perimeter Church in 1977, it started with a few small discipleship groups. Discipelship remains the heartbeat of Randy’s personal ministry and Perimeter Church. Randy just finished his 53rd consecutive year of discipling a few men, and through Life on Life Ministries, we are seeing discipleship transform lives and communities not just in Atlanta, but around the world.

Our Story

The discipleship model that propelled Perimeter church is applicable in every church across the globe. Now, that’s our mission.

Pastors around the world have shared with us that there is a leadership and influence gap between their church and the community in which they live. There are not enough leaders for the ministries of the church, much less to be salt and light in the community.

At Perimeter Church, life-on-life missional discipleship is the way that we are developing spiritual maturity in the lives of our people. For years, Perimeter was recognized for growth and innovation, but we realized that there was something missing – taking people to a level of maturity in their faith.

The church realized that life-on-life missional discipleship had been at the core of our leadership development, but it was not the culture of the church. It was not a movement. As we begin to apply the principles of Jesus’s model of discipleship to shape the culture of discipleship in the church, we saw a new level of spiritual depth develop amongst our people.

Life on Life Ministries was founded out of Perimeter, to help other churches to follow Jesus’ model of discipleship in their church.


Testimonies of marriages and lives being transformed are consistently being heard at our church.

– Bobby Suh, Christ Central

We are a ministry of a local church, designed specifically to help other churches.

Where We Work

WE PARTNER WITH CHURCHES AROUND THE WORLD

We work with local churches around the world to develop Life on Life hubs that can provide training for other churches in their region. This allows us to offer our relational training process outside of Atlanta. We are seeing discipleship movements ignite and hubs develop in Brazil, South Africa, Poland, Singapore, Manilla, Ireland, Australia, the Middle East, and Asia.

Bill Wood

Director of Life on Life Ministries

Bill Wood has been on staff at Perimeter Church for 18 years and was involved in the early formation of Life on Life Ministries. He has recently transitioned from Perimeter’s Executive Leadership Team and is now the Director of Life on Life Ministries and Global Outreach. Prior to joining Perimeter Church, Bill held executive-level positions in financial and technology corporations in a career spanning almost 50 years.

He joined the US Air Force at the age of 17 and during his enlistment he heard a clear presentation of the gospel for the first time and his life was transformed. In his new-found faith, he was introduced to discipleship as a few men discipled him. From those early days as a new Christian, he knew he would do for other men, what these men had done for him. That commitment to disciple men has remained from his time at the University of Tennessee and throughout his business career. In his present role, he encourages leaders around the world as they embrace a vision of discipleship for themselves and their churches.

Bill lives in Johns Creek, GA with his wife, Debby. They have three married adult children and four grandsons. When Bill isn’t reading a book, he enjoys walking and working on projects around his home and for his children. His grandsons represent a great opportunity to invest his life in a third generation of family. He and Debby continue to invest their lives in men and women. Bill has taken Psalms 92:12, 14 as his challenge for this stage of his life, to be fruitful, even in old age.
