“No one can serve two masters,” declared Jesus to his disciples (Matt. 6:24). However, Christians have spent the greater portion of the past two millenniums apparently trying to prove Jesus wrong. We have told ourselves that we can indeed have both—the things of God and the things of this world. Many of us live our lives no differently than do conservative non-Christians, except for the fact that we attend church regularly each week. We watch the same entertainment. We share the same concerns about the problems of this world. And we are frequently just as involved in the world’s commercial and materialistic pursuits. Often, our being “not of this world” exists in theory more than in practice.”
