The meaning of the Bible can be summed up briefly as the vindication of Jehovah God's name through the ransom sacrifice of Christ Jesus.
The tree of the knowledge of good and bad represented, to Adam, Jehovah God's sovereignty. That is, his right, as our creator, to decide for us what was good and what was bad until we, like children, matured to the point where we could do that for ourselves within the parameters of that sovereignty.
God created Michael first. Then Michael, as Jehovah's master worker, created everything through Jehovah's Holy Spirit or active force. The first thing that was created was the spiritual heavens. This was followed by the spirit beings, often called angels. Then the physical heavens, or space as we know it, including Earth, the stars, sun and moon. Then everything on Earth eventually concluding with Adam and Eve.
The angels existed for a very long time before man was created, and they had time to mature, like children, so that they knew what was good and bad from their creator. It is important that you understand that being created perfect is much like being born a baby. Parents see their newborn children as perfect, but think about it. They can't walk, talk, feed themselves, go to the bathroom properly - they are bald, toothless, chubby, defenseless little creatures. Perfect in the sense that they have great potential and innocence.
By the time man was created the angels had already reached their potential.
On the seventh day, when the creation was complete, God "rested." This doesn't mean that God was tired or that he stopped working, it means he set aside a period of time in which we were allowed to mature, as the angels had done. When we would have accomplished this we could, as the Bible says, enter into God's day of rest. In other words, the seventh "day" or more accurately, period, of creation continues to this day. So the knowledge of what is good and what is bad is the eventual possession of that maturity. The ability to decide for ourselves what was good and what was bad, predicated upon an acknowledgement of our own accord, of our creator, Jehovah's rightful sovereignty.
This is why, once Adam rejected that concept by deciding for himself what was good and bad before he had matured in able to best do that, Jehovah had to shorten his life from living forever to eventually dying. Because if he and his offspring, mankind, were allowed to live forever under those conditions, they would never reach that maturity and they would bring about an endless series of chaos and destruction.
So, in effect, Satan charged Jehovah with the crime of withholding some knowledge from mankind. He knew this wasn't true, but he wanted to try and seize control of the power that Jehovah's sovereignty represented even if it meant destroying all that it represented and everything else in the process. Even destroying himself. Like a jealous child breaking a toy so no one else can have it.
But to Jehovah justice is very important. You can't just wave away a crime due to the damage that has been incurred. So he allowed the charges against him to be tried, as in a court of law. He allowed Satan's theory to be tested in a manner of speaking. With the stipulation that 1. he wasn't going to allow it to prevent his original purpose for the angels and mankind from being fulfilled beyond what was necessary to establish his defense. That they should live forever in peace, in heaven and on earth respectively. And 2. that justice would be done.
From Jehovah's perspective the life he created, the life he gave us, is sacred. Belonging to God. According to the Bible our soul is our life, represented by our blood, so blood is sacred. To kill someone, or take their soul, requires the payment of the killer's own soul because it is taking something sacred to Jehovah. So the blood sacrifices represented a respect for or acknowledgement of his created life granted to us. For example, if a person was found murdered and no one knew who did the killing then they had to sacrifice a bull and spill its blood on the ground as a symbolic acknowledgement of God's possession.
Since we inherited sin through Adam then the only man who could pay the price for the blood of Adam, which had been perfect and without sin from the start until he did sin - was the blood of a man who was without sin.
So immediately after Adam's sin Jehovah put in motion the plan for all of this to take place while Satan's theory was being tested. In a basic sense the steps were as follows.
1. Select a group of people.
2. Form a nation for those people.
3. Demonstrate to them what was going on by establishing a law which they couldn't keep due to their imperfection, or the incomplete nature of their lack of the aforementioned maturity.
4. Provide a way out through a Messiah or Christ, namely, Michael, who volunteered due to his love for mankind and his father, Jehovah's purpose. So Michael came to earth as a man, Jesus the Christ.
