I believe that the message of Ecclesiastes is essentially a positive one. This may seem strange since the vanity of various human endeavors is such a major theme of this book. Nevertheless the total statement that Solomon made was positive.
He was saying, I believe, that even though every human endeavor lacks ultimate value, we should live life in the fear of God (i.e., with the proper recognition of Him). Furthermore we should enjoy life maximally as a gift from God. Ecclesiastes 12:13 is very similar to Proverbs 1:7 and 3:5-6. In both these books, as well as in Job, the fear of God is the prerequisite for successful living here and now.
The difference between Ecclesiastes and Proverbs is that in Ecclesiastes the emphasis is on the inability of every human endeavor to provide ultimate value. In Proverbs the emphasis is on the comparative value of living in the fear of God.
Solomon's attitude is very important for us to grasp to understand this book. He never lost sight of God's existence. He was not an atheist or even an apostate. The fact that Solomon kept God in view throughout the book enabled him to see that all is vanity under the sun. The person who disregards God does not say that. For him what is under the sun is all that is meaningful.
I do not believe Solomon did everything he said he did in rebellion against God. Some things were acts of disobedience, but many other things were experiments in living designed to discover the relative value of various experiences.
The major revelations of the book are three.
First, Ecclesiastes reveals that every human endeavor lacks ultimate value. All is vanity in that sense.
Solomon stated this thesis in 1:2.
Then Solomon supported his thesis with examples he took from nature (1:3-11).
Next Solomon appealed to various human achievements to apply his thesis. He did this first by citing his own personal experiments and observations on this subject (1:12-2:17). Then he referred to facts observable by all people that confirm the same conclusion (2:18-6:9).
Solomon next showed that every human endeavor lacks ultimate value by reminding us of the limits of human wisdom (6:10-11:6). He supported these assertions also with empirical evidence (what people experience generally in life). God's will will indeed happen. However man does not know God's plan fully. Therefore man does not know exactly what will happen.
The second major revelation of this book is that people should live life in the fear of God and enjoy life as much as they can. This is really Solomon's practical conclusion to the truthfulness of the thesis that he proved in 1:3-11:6.
Since death is coming we should enjoy life now, not in disregard for God, but in the fear of God (11:7-8).
We should enjoy life in our youth while at the same time remembering that God will judge our lives (11:9-10). Moreover we should behave responsibly in our youth since old age is coming (12:1-7).
The third major revelation of the book is its statement of what true wisdom is (12:13). God intends people to rejoice, but to remember God and to live with recognition of Him (cf. Prov. 3:5-6). Failing to fear God will result in a life of vanity. To fear God and live in harmony with His will will result in a life of fullness.
Let me point out some implications of the teaching of this book.
Conviction results in conduct that produces character. That is a basic reality of life regardless of what one's convictions may be. When we have a conviction that God exists and we live under His loving authority, our conduct will be obedience to His will. Furthermore responsibility and joy will mark our character. However if we believe that God either does not exist or is not worth consideration, our conduct will be disregard of His will, and vanity will mark our character.
To dethrone God is to lose the key to life. We may pursue many human endeavors, but all we will find is vanity, lack of ultimate fulfillment. On the other hand if we enthrone God we will enter into the fullness of life (John 17:3; Ps. 16:11).
