Hi, it may be because 90% of our brain is locked away in an unreachable zone that require a chemical map to unlock, because this is how God created the body. Most of our intelligence is stored in this area which is why our subconsciousness is so controlling. When salvation is administered to the body 100% access to the brain will be unlocked. In returning to The Bible the Tree of knowledge did have benefits for humans, but only God can allow us to achieve salvation, Romans 6:23, 1 Peter 1:5.
