Leaders in Living Rooms LILR 148 | Tom Mercer on Leading from 100 to 8,000 Through Personal Evangelism
In this episode of Leaders in Living Rooms, Sean Morgan sits down with longtime pastor and Oikos Movement founder Tom Mercer to unpack nearly four decades of ministry leadership at High Desert Church and the relational principles that shaped a church of 8,000 in rural Southern California. Tom shares candid stories about longevity, accountability, team chemistry, leadership development, and how the Oikos principle, reaching the world through the natural relationships God has already placed around us, became the backbone of High Desert Church’s growth. From navigating criticism and facility challenges to building a healthy staff culture grounded in prayer and friendship, Tom offers practical, grounded wisdom for leaders pursuing disciple-making and sustainable ministry.
