God's Sovereignty and Open Theism

>>> This is yet another paste from section 4 of my undergrad dissertation. However this section is one of my key arguments against Open Theism. Namely, if God creates primarily for His glory he must be exhaustively sovereign, if he did not create for this purpose then he is guilty of idolatry. <<<

4.2 God’s Purpose and Sovereignty
If you deny the creative-purpose that God creates to magnify His glory then you must assert God is guilty of Idolatry. If you affirm the creative-purpose that God creates to magnify His glory then you must assert God is exhaustively sovereign.

Open Theism inadvertently denies this creative-purpose by allowing God’s glory to be subject to the deterministic choice of man. ‘God created for the sake of loving relationships.’ Therefore God is not seeking the greatest good, namely Himself, and must therefore be seeking something in creation; the freedom of man for instance. When man does this, God holds him guilty of idolatry, why then would God allow Himself to be guilty of this same sin? Of course we know that God does seek the greatest good, so does create to show His glory which renders an Open Theist position biblically bankrupt on this point.

However, an Open Theist cannot affirm this creative purpose, for to do so would mean affirming God’s exhaustive sovereignty. For if God allows anything to hinder His ultimate purpose then he values the thing hindering more than the purpose hindered, rendering it not His ultimate purpose. God must therefore have exhaustive sovereign control over creation. Again this challenges the fundamentals of the Open Theist position which claims a self-limited God. ‘The openness view, with its denial that God can know the free decisions and actions of moral beings, simply cannot hold the Gospel in [the] same way.’
