Well, he knew he could not overpower God. So, why didn't he try
to repent and see if God will forgive him or not? Surely, he knows
he has no hope of winning the wars.
I often wonder what is Satan' motivation for doing evil back when I
was still a christian.
(This post is based on the assumption that Satan is evil,
and God is good, which is not my belief.)
Think about Noordin Mohammed Top.
He's still free to recruit suicide bombers and raising funds to
support his cause.
How do you know he will repent unless he is arrested and thrown
into jail?
