If some force has allready determined your future,
then trying to take care of yourself is useless..
Choosing to smoke or not to smoke would make no difference
to your health or that of your children.

Wearing a seatbelt while rideing in a automobile would have no effect on your safety.
But this is faulty logic..
Statistic show that people who take precautions suffer fewer
fatal consequences...
Carelessness can result in tragedy.

Consider another line of reasoning.
If God chooses to foreknow everything,
then even before he made Adam and Eve,
he would have known that they would disobey him.
But when God told Adam that he must not eat from
" the tree of the knowledge of good and bad "
or he would die,
did God allready know that Adam would eat from it ?
{ Genesis 2:16,17 }
