Roger Olson writes:

My acquaintance (a theologian) argued that open theism (and by extension for the reasons he gave) detracts from the glory of God–diminishing God’s glory. I asked him how anything can detract from or diminish God’s glory since everything, without exception, is designed, ordained and rendered certain (which he affirms) for God’s glory? To me this is a true conundrum of deterministic Calvinism (viz., Jonathan Edwards who is so revered and followed by these new Calvinists). It is illogical to argue that God designs, ordains and renders certain everything, without exception, for his glory and then turn around and say that anything detracts from or diminishing God’s glory.
