I agree with you, I do regard the creation as an expression of His love, and He didn't create us to be robots living in a dolls house. He created us in His image and gave us a will of our own with a conscience. He gave us commands to live by but He didn't force us to live by them as is evident when Adam and Eve took the fruit and ate it. In that sense, there was some semblance of freedom, but of course it was a freedom set within His boundaries and precepts because He is the Creator, rightfully owns His own creation, and we don't exist outside of His will.
Then we have the truth of what happened in Eden presented before us in the scriptures, and it's clear that Adam and Eve wanted to know more than what He had revealed to them at that time. They wanted to know what He knows so they could become like Him and have the knowledge of good and evil, and the only way they could get that was to disobey Him.
Where I think it all starts getting dicey with Calvinism is when it insists that it can fill in all the gaps of our understanding even to the point of insinuating that it was God's will that Adam and Eve disobey Him. It may not mean to deliberately imply that notion, but there is a danger that it does, and that by association implies that God wanted us to sin so He could save us.
Sorry, but I think that not only goes against God's own nature, but that it suggests that the only way He can find joy and glory is in contradicting Himself. By giving a command not to eat from the Tree of the Knowledge of good and evil, but secretly wanting A&E to disobey it, so He could glorify Himself by saving us. Hello? That's the part that no-one gets because it goes beyond the scriptures and is leaps and bounds in human logic and reasoning based on certain scriptures that don't even go that far.
I think that is why Josiah and MrJim are expressing caution in how far we all go with our theologies, because we don't know everything, we only know what He has revealed to us, and we must live from faith to faith and grow in the mind of Christ. That requires not always knowing everything, Abraham didn't know that when he stepped out in faith and went to sacrifice his son Isaac he was going to be stopped by God from doing it. And we have been called to the same faith, that means stepping out boldly in trusting God especially when we don't know all the answers, and that takes the courage and obedience of Abraham, not leaning on theologies as automatically having all the answers or processes by which we think we can second guess God's next step before we take our step.
