One possible explanation is that the illuminated serpent is not the bad guy in the story.
The serpent in the Garden of Eden story was not a literal snake. The Hebrew word for serpent also translates into the idea of to question. In other words, Eve in the story questioned what Adam had told her about the fruit of the Tree of Knowledge of Good and Evil.
Remember that historically the Jews did not have a character Satan the Devil until much later in their history. In the Old Testament the word that modern Bibles translate into Satan is a legal term, accuser. This would be the modern English equivalent to courtroom prosecutor.
Budbayview - Your question is as important as it is valid. Any spirit creation had direct access to the Almighty God of the Bible. They knew his scope and power. Any rebellion was an automatic death sentence with no hope of forgiveness.
Speaking from logic and reason, if the Bible were true, the only possibilities I can come to a conclusion are -
- God made spirit creation immortal and they cannot be destroyed.
- Being a spirit creation is a miserable existence and only God can end their suffering. However, the only way to get God to end their existence was to rebel.
