What’s the greatest novel ever written? Many readers would vote for Leo Tolstoy’s War and Peace, which, depending on the edition, can run well over 1,000 pages. Even after his novel was finished, Tolstoy continued to write—often until he was on the brink of exhaustion, unable to sleep, and on the verge of a breakdown.

One day a friend asked him why he kept writing and driving himself to the edge of exhaustion. He reminded Tolstoy that he was a wealthy Russian count with servants at his beck and call, and that he had a secure future.

Tolstoy explained that he kept writing because he was the slave of an inner compulsion and had a consuming desire deep within his bones. He felt that he had to keep writing or else he would go mad.

The apostle Paul experienced a similar compulsion, except that his drive was God-motivated. As he explained to his friends in Corinth, “the love of Christ compels us” (2 Cor. 5:14). His was a burning passion, an emotional fire, a spiritual force that made him share the good news of Jesus and His death and resurrection.

Such dedicated zeal has characterized many of our Lord’s followers throughout the years. May a spark of that fire burn in our own hearts.
