As the Teacher, Solomon, brings this book of wisdom to a close, he calls the reader to a faithful commitment to his Creator God. After again affirming the the hevel of life, he turns to offer a final word of wisdom. The word hevel has at least four senses throughout Ecclesiastes: transient, empty, ironic and frustrating, and each appears numerous times throughout the book. As Solomon concludes, he states the conclusion of the whole discussion is this - fear God (rever or be in awe) and keep his commands. Every human being is seeking to be satisfied, happy and fulfilled. Truly being fulfilled only comes as we are rightly related to God through Jesus. Satisfaction is only enjoyed through revering God and following his instructions for living. 

As Solomon writes Ecclesiastes, as the teacher (Qohelet), he expresses various aspects that everyone experiences in life. Throughout Ecclesiastes, Solomon rehearses the frustration, futility, irony and fleeting nature of life. The difficulties that exist are described throughout Ecclesiastes as hevel or vanity (futility). This theme consistently appears throughout this wisdom literature. Together, all of these frustrations can be rightly engaged, only as we rightly engage God through his revealed word. God offers the perspective and strength that we need to endure the hardships, trials and frustrations that life presents. This is why Solomon calls everyone to fear God and to keep his commands – to follow his instructions. This will not take away the frustrations of life, but it does offer a proper framework by which view them.
