Say, for arguments sake, an All-powerful God
exists. He must be timeless because He created
time. An All-powerful God will have completely
created all our actions and thoughts at the
Moment of Creation before we were born!
If our actions were decided before we were born,
then we have no Freewill. (Even if we think
we have.)
Freewill and All-powerful Deities are mutually
exclusive. If you believe in an all-powerful
deity then you must forfeit Freewill. On the
bright side, if you have no freewill then at
least you can sin without conscience.
If there is an All-powerful God then
it must follow that all acts of evil such as
murder, rape and torture were deliberately created
by God Himself. Oh dear!
In conclusion, you cannot choose to have
your cake and choose to eat it.
