Your vision of christianity is far preferable to the one I know of. To answer your questions: Honestly, my interpretation of Job is that God says "You are right". Right in what? That suffering has NO meaning. And the realization of this is the redemption. The "big other" is gone. That is what Job is about. Or as GK Chesterton, a famous catholic author said, when God asked Job who he think he is questioning God about his own suffering etc. what God really says is: "You sit there miserable because of your own suffering? Look around you. I screwed everything up!".
God wanted me to exist. Why? If I don't want to exist, what is God's reason for bringing me into existence if he foreknows that I don't want it. Suicide is condemned in christianity(perhaps not in orthodoxy) as the worst of all sins. That too I can not accept.
The sheperd of Hermas was even considered as canonical scripture by many of the church fathers, such as Irenaeus and Origen. It is contained within The Apostolic Fathers, so it has mighty importance.
You say there is no election and predestination? Well... That seems strange. Because in Scripture I find 25 places that speaks about election, and 5-6 places that talks about predestination. I also find a horrifying text from Paul in Romans 9 where he talks about how God creates some people in order to destroy them. And in Hebrews I find the same teaching as in the Sheperd of Hermas; those who fall away can never be forgiven, even if they want to.
You say the unforgivable sin is to believe that God is evil. Well, then it seems like I have committed it. You say that heaven and hell is the same place where God's love is responded to in different ways. How does that corresponds to scriptural words such as "punishment", "wrath", "vengeance", "retribution" etc? It seems rather to be wishful thinking? I find only a few verses in he bible that says God is love. Generally, the bible seems to say to me: "Love others and I will love you. Believe in Christ's sacrifice, and I will love you wretched sinner. Not because I love you really, but because I love my son. Now. Go love all your neighbours and enemies. If you don't I will cast you in that lake of fire along with your enemies." Even if you would experience God as Satan, why can't you be forgiven? Nothing is supposed to be impossible with God. No, in Scripture it is clear. God doesn't WANT to forgive them. "Shall never be forgiven" it says. Why. Because he is "Guilty of an eternal sin". Falling away in early christianity seems to have been equal to blasphemy against the holy spirit. This seems to me to be mind control and will to power. I fear christianity is true. But I must admit: Nothing in my life has made me so miserable and suicidal as the belief in the Christian God.
You said most christians would NOT agree that non-christians go to hell? hmm... That is not what I have seen. Neither among christians of today nor among the christians in history. If one is honest to what scripture and tradition has taught, the majority of the Jews were cast into a fire. That is a psychotic belief it seems to me. If I walk on the street thinking that the majority of the people there will go to hell (The gate is narrow as Christ says), then I get a panic attack. I was at a psychiatric hospital for a month because of this horrendous belief. It drove me to madness. I can't take it anymore. Show me the goodness of christianity. I can't find it anymore.
Regarding if I have the wisdom to say whether what God did was good or bad: He has given me the capacity to see what I see. And the conclusions I make of what he has revealed to me is that the world is a catastrophic mess.
BTW. Is Jehovah in the old testament the God of Jesus? Of course he is... Do you find the God who slaughtered the Amalekites, who wanted to stone homosexuals and women who had lost their virginity before their wedding to be Love? One really has to twist one's mind in order to say that it seems to me.
