And so, though your questions are important, I think the more crucial questions are these:
Again, Mr. Lentz tap dances around the issues put to him.
1. What happened to the perfect world described in Genesis 2 and 3?
Well, today seems a far cry from any sort of "perfect world." It's worth mentioning that, in those celebrated first 3 chapters of Genesis, there are some blatant contradictions about how God made that world. Also, that "perfect" world had some pretty arbitrary, senseless rules, like "Do not eat from this tree blah blah blah." Looks to me like God, with all his infinite foresight, was setting mankind up from the get-go.
2. Is today's world what God intended it to be, or is the world in the first 3 chapters and the last 3 chapters of the Bible more representative of God's intent?
You miss the fundamental irony of this question: How could God's will ever fall short of his intention? How could a perfect God, an omniscient, omnipotent, omnibenevolent God, fail to follow through on his intention? The very question you ask presupposes that your perfect God has failed at someting. There are two possibilities explanations for this: 1) It was never God's intention to create a "perfect" world; or 2) God is not omnipotent, omniscient, or omnibenevolent.
3. If today's world is not what God intended it to be, what if anything has God done about it?
Let me rephrase the question according to my answer to #2: "Since God has messed up and failed in his purpose, what has he been doing to correct his mistakes?"
The answer seems pretty clear: nothing. I know you're going to invoke the holy name of Jesus now, and talk about his great sacrifice, but even if all that is true, which I doubt it is, it's been over 2000 years since then, and is the world yet the "perfect world" that God "intended"?
