An omniscient God would have known that this problem would arise,
God allows for free will, and this allows for people to commit evil.
Then, people who are not able to understand this, blame the evil that people choose to do, on God.
The question isnt'.......>"Why did God allow that Rape".
The Question is.....>>>"Why does God get blamed for what a Rapist CHOSE to do".
See, for God to stop all the evil the PEOPLE choose to do, he has to
originally create them to have no desires and no free will.
Instead God chose to allow Humans to not be mindless Robot Puppets, but gave them the power of choice and desire., and all chose sin., including Adam and Eve.
God is not to be blamed for THEIR and OUR Choices.
