I was reading the book of Genesis when it dawned on me that the tree of knowledge was what possibly began our sense of time. I will do my best to explain how I see this.
And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it. And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat: But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die. - Genesis 2:15-17
As soon as we are born, we begin to age, decay. Eventually, our physical bodies die. The tree of knowledge gave an awareness of right and wrong. I believe that means knowing the difference between the two.
But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. And the serpent said unto the woman, Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil. And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons. And they heard the voice of the Lord God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the Lord God amongst the trees of the garden. And the Lord God called unto Adam, and said unto him, Where art thou? And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself. And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat? And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat. - Genesis 3:3-12
Not only were they not supposed to eat of the tree, but they also couldn't even touch it, or they would die. Adam and Eve wouldn't instantly die because I believe, they were not yet under the rule of time. Satan rules time and space - this third dimension in a sense and all time does is make things decay and rot. Eating of the tree then made them enter the third dimension, making them aware of their sin as well as their shame. The tree was desired to make one wise. Wisdom is a higher knowledge that has the potential to be used as an advantage, which the serpent described to have the ability to make them like gods. Up to that point, Adam and Eve only knew good, which is fully of God. After eating the fruit, they became acutely aware of their nakedness. They didn't have shame about it before because there was no knowledge of it. They were like children. They covered themselves instinctively, and they hid from God. Why would they hide from God? I think it is because they felt guilt and shame. They were exposed to those feelings and began to experience worry and fear after they became aware. Anxiety and fear are associated with the past and the future. You either feel guilty about something in the past, or you fear something in the future. They were no longer with a childlike sense of constantly being in the present moment. They now learned the concept of the past and of the future which brought them those feelings of guilt and fear. God asked where Adam was because he was no longer in the same consciousness as before. Something was different. God sensed that. He asked who had told him that he was naked, in other words, who made you aware of your evil? And then God suspected and insinuated that he had eaten from the tree that He told him not even to touch.
And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life; Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field; In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return. - Genesis 3:17-19
As a result of eating from the tree of knowledge, God cursed the ground. Before this, no work needed to be done to sustain their world. Now that time was a factor in their reality; they were forced to work hard to stay alive. Things became cursed as a result of their doing something that was related to the rebellion that Satan had exemplified. The world, this 3-dimensional reality, belongs to Satan. He dominates it. Time exists only in this reality. Man was created from the ground, and because of their sin, they would return to dust in the earth because time decays and makes things die. If they had not eaten, they would have remained beings that would probably never experience a physical death or even decay of their bodies.
And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever: Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken. So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life. - Genesis 3:22-24
They had not eaten of the tree of life, only the tree of knowledge. God wanted to prevent them from having the opportunity to live forever with the knowledge and awareness they now had. He kicked them out of the garden of Eden, which was probably existing in another dimension, and then set up guards to keep the way of the tree of life. Keyword: way. The tree of life was probably a way of being that emulated the highest good. Like Jesus Christ, since He is the way, the truth, and the life.
From this, I have concluded that Adam and Eve were once very childlike, having no sense of resentments, transgressions, and were always living in the present moment. Their awareness was limited to the now. The tree of knowledge gave them access to full knowledge of the past and knowledge of malice. Eating from the tree of knowledge opened Adam and Eve's eyes to their shame. They became aware of their sin and experienced the first feelings of guilt because they hid from God. They were in the now, but after eating the fruit, they became aware of the past and were then bound by time, which can be defined by making points of reference. In their case, their past sin. My mind is still in the process of making these concepts more understandable. I just keep seeing how things connect through the Bible, and they make sense to me. I could still be totally wrong since these are original ideas and theories I have from what I read, but my hope is that I'm a little right about something or at least going in the right direction.
