Orel: "Free will necessarily leads to choosing evil at least some of the time"
If that is wrong, then God was capable of creating a world with free will that no one chooses evil.
Wrong. Giving us a free will necessitates allowing us to choose evil if we should will to do so...creating the possibility (not a necessity) of someone choosing evil, beyond HIS control.
Now there is another doctrine apart from free will that does intimate to some people that GOD could have created a world without evil but didn't...the doctrine of HIS omniscience.
The current accepted definition of Christian omniscience that
"GOD knows all that can be known from eternity past to eternity future." implies to them that HE knew before their creation who would sin and suffer or even sin to end in hell which they accept includes the future state of our sinfulness as able to be redeemed or as unforgivable.
There are a number of verses that claim He does not desire anyone to end in hell nor does HE take pleasure in the eternal death (suffering) of the wicked which imply that
all HE had to do to create a world with a free will but without sin and suffering or hell would have been to just not create those people HE knew would choose to sin...easy peasy. But since that is not what orthodoxy accepts to be true, ie, HE did create people who do suffer and some will end in hell, then Christian theology is in self conflict: the definition of omniscience, HIS abhorrence of evil and the reality of sin in this world.
The resolution:
We accept that HE knows all HIS works from the foundation of the world,
Acts 15:18, in which it is accepted that
all HIS works refers to
that which all HIS decrees of creation created.
Thus if HE did not decree something into creation, HE did not know it. This allows the definition of our free will decisions to be by our will, not HIS will, to include the idea that HE did not choose, HE did not create, the results of our free will choices. HE did not KNOW the result of our free will decisions until we chose them and brought them into existence, ie, created them ourselves.
Against orthodoxy I contend HE did not decree, create, the results of our true free will decisions so HE did not know what those results were until we decided them for ourselves. This means that they are not in the category of
all that can be known in the definition of omniscience but outside of it (as
things which cannot be known to GOD) so the results of our free will decisions were unknown to GOD before our creation.
Thus we can logically have a true free will inside of HIS omniscience yet end with temporary sinners suffering for sin and eternal sinners suffering eternally for their sinful choices.
Since HE could not know the results of our free will choices because HE did not create them, for HIM to create us with a free will meant that the
possibility of someone choosing to rebel against HIM (or even everyone in creation rebelling against HIM) was 100%, however probable or improbable. That is, there can be no free will with the impossibility of evil not being chosen even by an omniscient GOD as you suggest.
HE cannot just NOT create those He knows will sin because He cannot know the results of our decisions before we choose them.
As well,
Possibility reduces necessary inevitability to the probable or the improbable.
