When God told the first couple:
" Be fruitfull and become many and fill the earth and subdue it,
and have in subjection the fish of the sea and the flying creatures of the heavens and every liveing creature that is moveing upon the earth,"
did he know that their wonderfull prospect of life in a paradise was doomed to failure?
Of course not.
{ Genesis 1:28 }

Taken to it's logical conclusion,
the idea that God foreknowns all decisions would mean..
that he is responsible for all that happens
including wars, injustices, and suffering.
Is that possible ?
A clear answer is provided by what God says about himself.
