In The Gospel of Matthew: God With Us, Matt Woodley writes:

A number of years ago, when I was playing in a friendly men's softball game, the umpire made a call that incensed our coach. My coach didn't agree with the ump's interpretation of a specific league rule. The game stopped, and a heated discussion ensued. Finally, the ump sighed as he pulled a rulebook from his back pocket and proceeded to read page 27, paragraph 3b, section 1.

"As you can clearly see," he concluded, "this rule means that my call must stand." Unconvinced, my coach yelled, "But you're not interpreting that rule correctly." To which the ump replied, "Uh, excuse me, I think I should know: I wrote the rulebook." After an awkward silence, my coach walked back to the bench, shaking his head and pointing to the ref as he told us, "Get ahold of that guy. He wrote the rulebook!"

Throughout his ministry, Jesus didn't just affirm and endorse the words of Scripture; he talked and acted like he had authored the Scriptures. He lived with the authority of the One who wrote the "rulebook."
