God may have known in advance that his creatures would commit sins, but he did not force them to do so. He knew absolutely what they would freely choose to do.

Objection:

• This argument works only so long as God is not seen as an all-powerful creator. If he clearly knew the sins his creatures would commit when he created them, he is responsible for them, much as a parent who allows a child to wander freely out into the road and get hit by a car is responsible for its death.
• In any case, this still evades the central question: how is sin possible? Where does it come from? It is difficult to view the capacity to commit evils as other than evil itself. If humans had been created free to choose, but able and willing always to choose good, would they not be better than they are now? Would they not in fact be exactly like God?
