Solomon wants to caution us against foolishness—the human’s flirt with the wicked, and also to encourage the converse—the human’s desire for that which is righteous.
It is truly a book to expose the truth and its consequences. King Solomon, the son of a humble shepherd-turned-king, tastes much of what life has to offer. He does not deny himself the pleasures of life. In the end, after much study, contemplation, and reflection, King Solomon states his thoughts on the matter using words that are common to life.
What is “real” is what gives meaning to life. And then there is a link that connects it together. It is this: That which is real is connected to the Creator in both wisdom and purpose. Solomon is seeing life by looking back over his shoulder, much as I am as I write. He finds that it is beginning to make sense.
