open theism is incompatible with scripture: omniscience and ignorance are opposites.
Psalms 139:15-16
My frame was not hidden from You,
when I was made in secret,
and skillfully wrought in the lowest parts of the earth.
Your eyes saw my substance,
being yet unformed.
And in Your book they all were written,
the days fashioned for me,
when as yet there were none of them.
