Wanting not to walk with God but experience walking with God makes no sense unless you are merely after the benefits.
Who are you talking about? I don't believe any of this, so it can't be me. I'm arguing that the god in the story is condemned by its own actions.
Even if there were sinless people, namely, people in perfect unbroken communion with God, is that you?
Since sins are forgiven through Jesus Christ God is still open to you should you so choose. If you choose to walk away from God how can you be in communion with him. In other words, if you don't want him is it reasonable to complain that you do not have him?
It's got nothing to do with me. As I said (and you're still ignoring), in the story, either we (humans in general) have a choice to be sinless or we don't. If we do then some people would make that choice, and the bible is wrong to call us all sinners. If we don't then god is unjust in condemning us for being the way it chose to make us.
Back in the real world, there is no reason to take the idea of this god seriously in the first place, so it's not a question of "walking away". If this god of yours exists in reality, it's compounding its injustice by playing a cruel game of hide-and-seek.
Taking the effects of of the fall on himself doesn't mean you are monstrous. Would you not relieve your offspring of the harm they might do to themselves by taking the cost of their actions on yourself?
But it's god that made up the monstrous and unjust "effects" in the first place, and it's god who decided that the bizarre act of torturing itself to death would make things all right again. It's like a parent deciding that their child should be beaten with a big stick if it eats an extra biscuit before dinner and then, when they do, takes to self-flagellation instead (and then still threatens the kid with the beating if they don't worship them).
Look, the story goes that god made two people with no knowledge of good and evil, put a fruit tree in the garden, told them not to eat the fruit, and then added a talking snake to encourage them to do just that. One really doesn't have to be omniscient to imagine how it might go wrong. Then it visited the consequences on the whole of humanity, when it wouldn't even have been fair to do it to Adam and Eve themselves (because they didn't know right from wrong), and then instigated this bizarre sadomasochistic nonsense with the incarnation, torturing to death, and magicking back to life, so that if we now grovel enough and believe this silliness, we might not be condemned for being condemned for something somebody else did a long time ago.
This is nothing like justice and it's nothing like a parent-child relationship - it's just bizarre, nonsensical, and horrifying.
