I’m concerned that many Christians are content to hunker down in Christian echo chambers and ignore the broader cultural conversations about faith in God. Some treat the gospel like a fragile heirloom that should be covered in Bubble Wrap, hidden in the attic, and thus preserved for future generations.

I tend to think the gospel can hold its own. The gospel won’t be intimidated or overshadowed by rival truth claims. As the famous preacher Charles Spurgeon said, you don’t defend a lion. Unchain it and it will defend itself.

This book [Christ or Chaos] is about the gospel minus the Bubble Wrap. It’s about the gospel’s power unshackled and taken out of the attic. We need the gospel more than it needs us. And we see the gospel best when we actually see through it—when it’s like a pair of reading glasses giving us a clear vision of reality.

That’s why Christians should never be ashamed of the gospel in the private or public domain, in our churches or in the marketplace of ideas. We shouldn’t shiver at the thought of subjecting the gospel to the test of sincere scrutiny. If it’s false, then we have nothing to gain, and if it’s true, we have nothing to lose. As C. S. Lewis once said, “One must keep on pointing out that Christianity is a state- ment which, if false, is of no importance, and, if true, of infinite importance. The one thing it cannot be is moderately important.”
