As a previous Christian, I can verify that Christianity only makes sense if you go into it assuming it to be truthful and make sense. Or, rather, that if it doesn't make sense to a human, it's OK, because only God is supposed to truly understand..and Christians are fine rolling with that. But from an outside, logical, objective analysis, it and most other religions or religious-like beliefs (or "relationships", whatever) actually make zero sense. Of course, a religious person is almost always discouraged from even considering these outside views as serious or making true sense, so, really, both sides don't and can't understand or make sense of "the other side."
The real question I have is this: Why would God give us free will knowing full well every action that would occur in the future and then choose to punish us for that? If you say God didn't know what would happen, then you don't actually have a God, because God is clearly defined as being omniscient, omnipresent, and omnipotent.
So, God had to have known full well than humans would sin down to every last detail in the event. Of course, if God knows everything that will happen, how do we have free will? We would perceive ourselves as having free will, but God, being outside of time (according to what I was taught), would be able to see the entirety of humanity's existence.
I'm also suspending logic here, because God is apparently outside of time, yet God clearly acts within "our" time according to the Bible. So, let's ignore than inconsistency. Even then, our perception of time and free will would be more akin to an illusion than anything else.
So, in this case, humans wouldn't have free will, or at least not truly free will (which I'd argue is the only kind of free will). Our entire existence would have already been predetermined. So, God would have known we would sin no matter what. In a sense, it would more appear that he is at fault for us sinning, as he was the one that laid this path out for us (or, at least, saw the path in its entirety from the beginning and did nothing about it otherwise).
No free will. God knew we would sin and did nothing about it even though he is against sin. God still chooses to punish us with Hell if we don't repent. Why? How can that seem anything other than petty, unreasonable, and illogical to anyone? It just shouldn't make any sense at all, period.
Imagine if God were instead a computer programmer, and humans are just AI implemented in one of many worlds. The whole notion of sin and punishment for it would be akin to the programmer knowing full well he left bugs in the AI code, knowing that it would cause unwanted results from the AI, and yet still getting angry at his own doing as though it was the AI's fault from the very beginning.
God is no god at all.
