Eden was a handcrafted dwelling place for both God and humans. In this perfect space, both the Creator and the created could exist together. Since God created everything tov meod (Hebrew for very good), this would include his creation of, and decision to place the tree of life and tree of the knowledge of good and evil in the Garden.
I have heard it taught humans should be ignorant of evil, that we should avoid knowledge of it. This seems contrary to God’s design, because he specifically put these trees in the Garden in proximity to humans. To take it a step further, Eve and Adam did have at least some knowledge of good and evil before eating from the tree. What I mean is they understood anything in the Garden was good to eat and enjoy, except for the tree of the knowledge of good and evil.
So where did they get this basic knowledge of good and evil? From God! God never says they should have no knowlege of evil (afterall he told them what evil would be in this case). And there was nothing evil or sinful about the tree itself, after all, God deemed it tov meod. What God did, however, was govern the use and access to these trees. They are not evil, but interacting with them can only be done on God’s terms.
It seems to me that this illustration in the Garden teaches us that we should not seek to determine good and evil for ourselves. It seems God had a plan for the trees and the humans, but the desire of the humans to bypass God is the ultimate sin. Rather than submit to God’s wisdom and knowledge, functioning in their created role, they chose to usurp God by attempting to become like him. The saddest part is the humans were already like God, created in his image. Had they walked with God and obeyed him, perhaps those trees could have been used for their proper purpose. Unfortunately, we will never know this side of eternity.
It strikes me as spiritually significant that God has created tools that are useful for his purposes, and has placed these tools within our reach. But these tools can be catastrophic to us if we misuse them. Life is full of objects that can be simultaneously tov, but harmful.
Let’s use an oversimplified example. God created humans with speech abilities. God created this “tool” for humans because he wanted us to speak. But if misused, our speech can cause catastrophic damage to others and ourselves.
Scripture repeatedly calls us to gain wisdom! But wisdom by itself isn’t enough. Simply having wisdom can have catastrophic results (just look at the story of Solomon!) What is important is where we find our wisdom, and how we apply it. Sex is a beautiful gift from God, but when it occurs beyond God’s intended purpose, it no longer functions in a good way.
We must rely upon God’s wisdom and trust his leading in navigating life. If we rely on our own abilities, or lean on our own knowledge and reasoning, we too will fall victim to the sin of the Garden.
