“On any given stretch of road there are more and more warning signs. ‘Lane closed.’ ‘Mud on Road.’ ‘Slow Farm Vehicles.’ Not to mention signs telling you how fast you’re allowed to drive, warning you there are police cameras waiting to catch you if you speed, suggesting you stop for a cup of coffee before you get too tired, and telling you how far it is to your destination. Jesus ends the great Sermon on the Mount with a set of warning signs. If you’ve come this far with him, you need to know it’s not just a matter of holding on to the steering wheel and hoping for the best. You need to concentrate, to take note of danger, to realize that you can’t presume on anything. You’ve got to keep your wits about you” (Wright, Matthew for Everyone, Part 1, 75).
