Ok, I think I understand now. You're saying that Eccl. doesn't offer a way out of the cycle and it suggests fearing G-d because there is no other choice.
Why do you view the cycle as something that one should want to escape, rather than a neutral component of reality? Rather I should say, how do you understand this cycle and what benefit would be gained in escaping from it?
I see the pessimism, and I think that's what he was aiming for: everything about the physical world is emptiness and suffering and the only worthwhile pursuit is in the spiritual.
Because it works for me.
I can achieve happiness in life through my own efforts. Through meditation and self-determination.
Other folks try to control you through your emotions. Through guilt, through fear, jealousy, by withholding love. I see the fires of hell as the passion of emotions which causes people to react and in a sense imprisons them. Temptations and desires. It's not that emotions and bad or even the physical world is bad, it's that a person without self-determination is a slave to the desires and temptations caused by emotions.
I'd much rather be in control and determine my emotions, my desire and my actions. Being able to do so I find leads to a state of consistent happiness. Understand even fear, anger, hate have their use, but I control them.
This frees me from suffering, which to me is being a slave to your desires.
This to me answers the issues brought up by Ecclesiastes.
The other problem is knowing exactly what are the commandments of God? The 10 commandments? Which their application through out the Bible is a bit vague. The 613 Jewish laws? The 30 or so commandments by Jesus. There is to me no clear understanding of these required commandments. Folks have their own beliefs and ideas of what they are and argue about them constantly.
And this day of judgement. There is no actual knowledge of this, just faith and belief. People say this is true but there is no real validation of it. Just something people believe will happen.
So I can choose to act in some way I assume God wants me to act again assuming I may be judge for my adherence to this commands which people can't seem to agree on what they actually are or I can improve my life. I can take charge and control my life right here and right now. It's not some vague idea of laws that God wants me to follow assuming at some future date I will be judge for how well I did. It's something that affects now and each moment of my life.
I choose my purpose, I choose my goals. I don't need God for that. And, if I end up being judged, I'll be judge for who I am, not who I think nor who other people tell me God says I should be.
