From Phil Johnson’s message at the Shepherd’s Conference:
Contemporary evangelicals’ resistance to boundaries is especially hard to reconcile with the fact that pastors (the word means shepherds) are expressly charged with guarding the flock and keeping predators out of the fold. And there simply is no realistic way to keep sheep in the sheepfold and wolves out if you refuse to observe any boundaries. In John 10:7, Jesus famously said: “Truly, truly, I say to you, I am the door of the sheep.” I cannot envision any useful purpose for having a “door [for] the sheep” if there is no sheep-pen or enclosure of some kind with well-defined, secure barricades, sturdy fences, or a protected perimeter of some kind.
But mainstream evangelicals have been indoctrinated along with the rest of postmodern society to think walls and borders are inherently sinister. We’re conditioned to favor a whole different set of more stylish and more politically-correct values: tolerance, openness, diversity, mystery, indecision, broad-mindedness, and liberality. It’s considered humble and generous to entertain perpetual qualms about what we believe. We’re not supposed to think any single perspective can righteously claim to be true to the exclusion of all others.
So today’s evangelicals bend over backward not to sound the least bit dogmatic. Because certainty is perceived throughout our culture as a kind of cruel arrogance. Clarity, authority, careful definitions, and firmness are likewise looked upon with deep suspicion. Stating your beliefs with settled conviction is a sure way to start trouble these days.
