Even if God does give us some reward for good behavior, this means that it's still beyond your control. Everything which is beyond your control or when someone else who is much more powerful than you is controlling you or worse is taking your life while giving you nothing in return is not a good thing in my opinion unless it is some sort of process of becoming part of God or actually working together with God and leaving this earthly life and the human form forever.
I think that living forever on Earth in human form is the real Hell unless you are freed from the human form and earthly life and either become a physical part of God or become some sort of God yourself, working togehter with God and becoming a force for creation.
I believe Jesus.
I believe the reward is for trusting and believing God/Jesus. being saved is not a reward for good behaviour but a positive response to the will of God
As for control. We have control of our response to His will and the teachings of Jesus.
I believe when those who believe Jesus are raised from the dead we will be changed and made good again. And this world will be renewed and also made good again. i believe we will exist for eternity on earth in perfected bodies, it shall not be a hell on earth, as the earth is now.
I believe i am working with God. Although it is His work that He is pleased for those that believe him to take a joyful, but in the end, ceremonial part in.
I will be freed from this faulty form, i will not become a god, but i will be with God forever.
All Praise The Ancient Of Days
