On average, each of us has 8 to 15 people, whom God has supernaturally and strategically placed in our relational world so that He might use us to both demonstrate and discuss faith. The Greeks used one word to describe this personal world—OIKOS, or “extended household.” OIKOS is not an evangelism program. It’s not an event. It’s not an emphasis. The oikos principle is the heartbeat of Christ’s Church. Jesus designed it, modeled it and taught us how to use it. Since then, it’s been instrumental in bringing 95% of believers into the body of Christ. Tom Mercer has not only experienced the oikos principle firsthand, he has committed his life to helping the church understand and utilize this incredibly simple yet effective strategy for changing a world that just might be smaller than you think!
Tom has been married to his wife Sheryl for thirty-seven years, and they have been blessed with three married children, who have in turn blessed us with the greatest core oikos imaginable—nine grandchildren. Tom received his formal education at Biola University and Talbot Seminary. He has been the Senior Pastor and primary teacher at the High Desert Church in Victorville, California since 1984. During that time, HDC has grown from 125 regular participants to over 12,000; from one campus to four.
He has authored two books, 8 to 15: The World Is Smaller Than You Think and Common Sense Is the New Brilliance. These books highlight the oikos principle, which Tom believes is the simplest and most effective form of Kingdom growth that Jesus gave us.
