“There’s a story in the biography of George Whitefield about a man named Thorpe, who was a bitter opponent of everything that is holy. He and a group of his friends—all of them young, rebellious thugs—conspired together to mock and oppose George Whitefield’s evangelistic ministry while Whitefield was preaching in Bristol, England.
George Whitefield had severely crossed eyes, if you have ever seen a realistic likeness of him. And these guys used to refer to him as “Dr. Squintum.” They called their little gang “The Hell-Fire Club,” and they disrupted meetings, mocked Whitefield on the streets and in public places, and generally tried to make his ministry a reproach in their community. Whitefield’s preaching had already made a deep and lasting impact in Bristol, and these young ruffians hated him for it. So this guy Thorpe got one of Whitefield’s published sermons and took it to the local pub, where the “Hell-Fire Club” was gathered to drink together while they make a burlesque of Whitefield.
Thorpe was apparently pretty good at doing impressions, and he had all Whitefield’s mannerisms and gestures down pat. So he stood in the center of this pub and crossed his eyes and began to deliver a derisive rendition of Whitefield’s sermon. But in the middle of the sermon, the Word of God pierced his heart, and he suddenly stopped and sat down, trembling and broken-hearted. Right then and there, he confessed the truth of the gospel and gave his heart to Christ. His aim was to taunt and ridicule, but he accidentally converted himself! Or rather, the power of the Word of God penetrated his soul and cut him to the heart. He became a preacher himself and quite an effective evangelist, because he knew so well the power of the Word of God to penetrate hardened hearts.
Notice that the Word of God pierces to the very depths, “even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.” It probes to the deepest recesses of the heart, no matter how hardened or how closed the heart might be. In fact, only Scripture can do that.” (Hebrews 4:12-16; 2 Timothy 4:1-5)
