Lucifer had been working on a dilemma. The logic was indisputable.
His conundrum kept him from directing the other angels in their affairs as he sought the answer.
He was a leader not a follower and didn’t ask advice, he gave it.
God told him he lived in pride, which was a sin.
The Arch Angel Michael tried to warn him that if he chose to go the path he set himself on he would be forever lost.
There can be only one, said Michael.
Lucifer stood saying, “Hail to the King baby!”
Then departed heaven to become a King.
