Eric Spivey

Findley Edge’s challenge in The Greening of the Church drives Eric’s ministry:  “The gift of salvation and the call to ministry are one and the same.”  His ministry has centered on this connection between discipleship – saying yes to Jesus – and missional living – God’s vocation.  His experience includes ministry both outside and inside the local congregation.  Eric enjoys coaching individuals and congregations in discovering and living out this calling in 21st Century America. Eric also serves as lead pastor of First Baptist Church of Cornelia, Georgia, enjoying life in the North Georgia Mountains.

alan arnold

A wise one said, “We are all just helping each other home.” When fellow travelers seek assistance in finding the harmony of wholeness and purpose constituting their “home,” Alan is positioned to help. He has served as a guide and friend to many and delights in helping people claim their personal and professional potential. Alan assists in recognizing capabilities, as well as the desires of the heart, while coaching individuals and teams toward maximizing their potential.
