That is a good question. I think that if he couldn't do it in a simpler way, then there was no other way. This is key from that link: "God’s wrath and God’s mercy display the riches of His glory, but we cannot see either without the fall of mankind. We would never know grace if we had never needed grace."In my scenario, he creates a garden utopia of unending love and bliss.
In reality, he created that exact thing, but with a built in fatal flaw that he knew would be implemented, to ultimately bring himself glory.
‘God foresaw Adam and Eve’s fall. He created them anyway, in His own image, to bring glory to Himself. They were given freedom to make choices. Even though they chose to disobey, their choice became the means by which God’s ultimate will was carried out and by which His full glory will be seen.’
Why did he need to do all that? If he’s God, why couldn’t he just reveal his full glory in a much simpler way?
Maybe think of it this way. Look at any four or five-year-old; any young child. Do they truly love their father? Do they know what love truly is or know its depths? When their father gives them something, maybe a new toy, are they truly thankful? They might say "thank you" because they've been taught that is the right thing to do and maybe at some basic level they do feel thankful. But do they truly know the heart of their father? Do they know the depths of gratitude and why they should be so thankful? More could be said, but the point is this: do young children really know their father? Once they grow up, then they come to understand (hopefully) the depths of a father's love and are genuinely grateful for it.Imagine my scenario again- paradise. And imagine that he simply imparts to them or infuses them with the fullness of his glory and suddenly they’re worshiping him for all eternity. I mean, I’m no god, but in my scenario the deity is worshipped forever in perfect harmony with beings that never knew a moment of death or suffering.
God set things up on this earth in a way that, yes, we would fail, but through that failure, we could come to truly know him and know his heart. He sent his only Son to die for us, so that we could be forgiven and reconciled to him; there can be no greater example of love than that, no greater reason for gratitude, no greater way of actually knowing his heart than that.
You may not find that convincing, but at some point, you need to trust God that there simply was no better way for us to come to truly know and love him.
