Sea Breeze: When a person abandons the rights to himself and 'dies" to himself for Christ, he immediaetly becomes an adopted member of God's family
This doesn't change the dynamic. As you note, we break god's rules all the time, and we have absolutely no way to recover from this on our own merits. Even those who want nothing more than to serve god as perfectly and purely as they can, fail constantly. Humanity is inherently incapable of following god's rules and commands.
The only way to avoid this would be to have our free will stripped away, to become someone -or something- that we are not. So, I will either spend eternity incapable of independent thought/action, or I will spend eternity suffering because I invariably broke a rule or crossed a line. The belief appears to be that god won't act this way, but that approach isn't logical. That's not who god is.
Sea Breeze: How do you arrive at universal correct reasoning in a chance universe?
I'm not quite sure what you mean by "universal correct reasoning." You mean a moral code that everyone, everywhere, will agree with? Assuming such a thing is possible, you get there by trial and error. You experience things, you learn, you adjust. Over and over and over.
This is why so many old religious texts seem out of touch with modern times. They reflect the state of human moral reasoning of their time. Time goes on, we gain more experience and learn more, we update our moral guidelines, and the cycle continues.
Sea Breeze: You are standing on Christian ground when you appeal to reason.
This was the problem I ran into, when I was trying to make a case for god. Once I stopped relying on presuppositions, I had no basis for anything I believed. Stating that god is real, or that reason is impossible without god, allowed me to skip past the difficult parts and demand that others disprove or account for something that I did not prove or demonstrate in the first place.
The thing is, even if we grant the presupposition, we now have the ability to reason. And that means we can make determinations about moral behavior without having those rules imposed on us without explanation. I don't have to 'get my own reason.' Using the god-given ability to reason allows me to remove god from the moral equation. If god's own gift allows me to set him aside, then perhaps that is what god wanted all along?
