Why even bother having a “tree of knowledge”?
God put the tree of knowledge of good and evil in the Garden of Eden to give Adam and Eve a choice – to obey Him or disobey Him. Adam and Eve were free to do anything they wanted, except eat from the tree of knowledge of good and evil. (Genesis 2:16-17) If God had not given Adam and Eve the choice, they would have essentially been robots, simply doing what they were programmed to do. God created Adam and Eve to be “free” beings, able to make decisions, able to choose between good and evil. In order for Adam and Eve to truly be “free” – they had to have a choice.
