Look .... we need to begin to understand that is a purpose for all things that happen.
For if God did not allow for murder? Satan and all the angels would never know why God condemned him.
For all Satan did? Was as follows.
Isaiah 14:12-14
How you have fallen from heaven,
morning star, son of the dawn!
You have been cast down to the earth,
you who once laid low the nations!
You said in your heart,
“I will ascend to the heavens;
I will raise my throne
above the stars of God;
I will sit enthroned on the mount of assembly,
on the utmost heights of Mount Zaphon.
I will ascend above the tops of the clouds;
I will make myself like the Most High.”
Satan only had a "thought."
No one coming out of that previously perfect world could understand what such a desire could mean.
But, the Lord in his omniscience knew what the thought intended.
Jesus said if a man only lusts in his heart towards a woman? That as far as God sees?
That man has already committed that act he lusted for.
Likewise... When Satan desired to ascend to heaven and make himself to be like the Most High?
What was in his heart? Why was it so bad as to condemn him?
When God allows for a revolutionary low life to conspire against a king and take over his castle?
Then assassinate that king, and take his crown for his own?
The bad result became an overt manifestation of his desire.
That is when the angels could be shown to began to understand what Satan's desire was towards the Lord.
For, when Satan in wanted to make himself like the Most High? He assassinated the Lord in his heart!
But no angels knew what murder was, nor death!
That same desire replayed when the Pharisees wanted Jesus murdered so they could claim his position
of being the loved one over the people.... (Pilate knew the Pharisees were jealous of Jesus.)
Without death and murder by jealousy? How could Satan and the angels be shown what Satan desired towards the Lord?
Show angels who had been living in a perfect world, to know what Satan really desired to do?
Solution:
God had to allow for fallen men (who think like fallen angels) to murder out of jealousy ...
Same goes for all crimes by men. For they all represent hidden motives, that at one time, angels who desired evil
could not understand. Without an example they had no idea what their evil desire would cause.
Not unless God illustrated their desires outcomes by means of displaying overt expressions by fallen men. .
That is one reason God allowed for the fall of man.
For fallen man's actions represent fallen angels desires, being the children of the serpent.
That is why it says.... "his seed" in Genesis 3:15.
And I will put enmity between you and the woman, and between your seed and her seed.
He will crush your head, and you will strike his heel.”
grace and peace .........
