The Arminian Problem in Simple Terms
by Phil Johnson
If God knows the future with certainty, then the future is (by definition) already predetermined. If tomorrow is predetermined and you don't want to acknowledge that the plan was decreed by God, you have only two choices:
1. Some being other than God determines the future and is therefore more sovereign than He. That is a kind of idolatry.
2. Some impersonal force does the determining without reason or coherence. That is a kind of fatalism.
So anyone who denies that God preordained whatsoever comes to pass but wants to avoid both fatalism and idolatry is logically compelled to deny God's omniscience.
That of course, is precisely the rationale that has led so many to embrace Open Theism.
The more sensible option—and the biblical one—would be to abandon Arminian presuppositions and acknowledge that God declared the end from the beginning, and that He works all things according to the counsel of His own will.
