The conclusion of the matter that Solomon comes to after he concludes this book is the realization that life is meaningless without God. The book is to convince man of the worthlessness of any world view that takes into account man’s world alone, i.e., how life would be without God. Today we see this throughout Europe, and we see the beginnings in the United States.
We need to pray that our focus returns to God.
