Christians like to quiz each other about their favorite book in the Bible. Finding out how people experience Scripture—especially those who write books about the Bible—is a natural interest to us. When asked which Bible book is my favorite, I say Ecclesiastes. Should people raise their eyebrows and ask why, I give them two reasons.

First, it is a special pleasure to read an author with whom one resonates.

As his official testimonial or third-person testimony (it might be either) in 12:10 shows, this man took his instructional task very seriously and labored to communicate memorably. Whether he was the Solomon of history or someone impersonating him—not to deceive but to make points in the most effective way—we do not know. All I am sure of is that each point has maximum strength if it comes from the real Solomon at the end of his life.

Whoever he was, Qohelet was a realist about the many ways in which this world gives us a rough ride. But while temperamentally inclined to pessimism and cynicism, I think, he was kept from falling into either of those craters of despair by a strong theology of joy.
